YES. That's how I always remembered it... that 720p is 60fps progressive and 1080i is 30 interlaced frames when combined creates the 60fps. Now that I have the N9500GT I'm back seeing 60fps regardless of original broadcast format. The biggest thing to watch is the steadiness of the scrolling white line -- it's a dead give-away as it'll tear or be jerky whenever frames are dropped, or judder.
IF you want to prove this to yourself, you could locate an old version of MP 1.0.0.0 and playback a .ts file -- since it's not using textures it will yeild the 60 fps on your 7050PV. Have you been looking for a new Video Card? Seems I just hit the market at the right time getting the $30 MIR... you might should keep looking for a week or so... these things are alwasys going on sale!

InsideHW - ATi Radeon HD 4670 vs. nVIDIA GeForce 9500GT
The Nvidia 9500 is more expensive compared to the ATI 4670 (at least in Australia), and it doesn't perform as well (at least on gaming benchmarks, which I admit are not the focus of what we are talking about here - why do they rarely benchmark h.264 playback in these reviews???). From what I read, these are supposed to be the two equivalent cards in the Nvidia / ATI camps.
I recently upgraded an ATI 3450 to this model. The 3450 just didn't have enough grunt to de-interlace 1080i and ha the h.264 codec. I probably should have gone for the 4550 for the passive cooling, but I thought the extra grunt of the 4670 was worth it, and the onboard fan is pretty quite anyway.
Another option for those struggling with 1080i / h.264 is to use CoreAVC if you have an unpowered GPU but on ok CPU. CPU with ffdshow vs coreavc dropped from around 80% to 30%. This is what I was doing with the 3450, and it worked ok. Personally, I find DXVA a bit hit and miss at the moment (ie bad encodes, subtitles - yes I know the later is being worked on for 1.1.0), so its probably worth having the "software" option as a backup anyway.
That article has another good reason why the ATI 4670 is a good choice. Check the table in this post:

I think I'm starting to sound like an ATI biggot..... sorry.
Does somebody have experience with the Nvidia Decoder NVIDIA PureVideo Dekoder
under the current MP version?
I am wondering whether this might solve the deficiencies that have been mentioned in this thread. Or does the decoder nothing have to do with these stuttering problems?

NOTHING to do with the issue... Actually I've found it is (possibly) a bit slower (or has interaction issues w/AC3Filter) on these last releases of MP. So, don't wrry buying PureVideo if you already have a Cyberlink, or some other working codec.
Are you using a Hauppauge HD PVR to capture? I've been doing a lot of reading on the 1080i60 format. Seems that sports (like the NHL finals on NBC) are shot in 1080i60. Each field (there are 2 when it is interlaced) capture captures 1/60th of a second. The second field capture captures the next 1/60th of a second. Then the de-interlacer (depending on its quality) should produce a 1080p60 output using some motion adaptive techniques. Obviously it won't be perfect but should still look fairly smooth as de-interlacers are alway improving.
Now my TV must have a decent de-interlacer as it is receiving a 1080i signal from my STB. Yet the smoothness of motion is very lifelike. When going through MediaPortal, like I said before it is not as smooth; almost like it is deinterlacing to 24/30 fps.
So I guess my question is: Does the HD PVR capture the 1080i60 format completely so that a decent deinterlacer can create a 1080p60 display? If so, the I will invest in a card and try it out. Otherwise, I'll just stick to 720p.

I'm not capturing anything. Period. As you see in My System (click on the left there... fill in yours when you get a chance) I'm using the Hauppauge 1600 ATSC tuner card (and an ATi as a second tuner). ATSC is a mpeg-2 stream which either is written to HDD or decoded for LiveTV. Either way it's already a mpeg-2 stream. I'm not trying to get into a discussion on the merits of how 720p vs 1080i work... all I know is the TV networks using 1080i are one format and the 720p are another... I have (again, in My System) a Sony projector with a 1280x720 native panel, thus I send that on my HDMI cable. What happens INSIDE my PC to create that is transparent to my PJ as it always sees 1280x720. (Same goes for my DirecTV -- I have the switch to send all material as 720p which saves the PJ from re-syncing when I switch between network formats.) Oh, my PJ will DO 1920x1080 and 24p material, but why? The PC does the job and my PJ's display is constant -- no resync.
I really don't understand your question, or how you can "stick to 720p" -- if you want to watch a network that transmits in 1080i (NBC, CW, CBS, PBS) then you have NO CHOICE but to receive their 1080i mpeg-2 stream and decode it... that's all there is.

My STB has the option to force a specific resolution out if I want. So I could watch a 1080i station with a 720p signal to my HD PVR. That is what I am doing now. So you are in a different boat than me. I am doing H.264 decoding in addition to deinterlacing. You are just MPEG-2 decoding which I don't believe is as expensive.
I will post my specs when I get home. I'm at work now. I do appreciate your help. I am technical and have a comp. sci. degree, but have never really studied much on video codecs etc. I've also had trouble even enabling hardware acceleration. It would just be a blank screen. Perhaps have the new card would fix that too.

no the 1600 has about 25 fps on 1.0.0 and 6 fps to 25 fps on 1.0.2. I attached some screenshots which describe the problem.
My 1.0.0 recordings are running all fine with MPC. There is a recording (Stern TV, RTL) made with 1.0.0 which is playing fine with 1.0.0 but this recording is not playing with 1.0.2 and with WMP. But some other recordings (Rock am Ring, MTV) made with 1.0.0 are playing fine with 1.0.2 and WMP.
You see my CPU usage on the screenshots. What do you think? Should I replace the graphic card or the CPU?
Please remember that I only watch SDTV on a 720p (1280 x 720) screen.
The system information were out of date. I have 2048 RAM and SP3.
Sorry what's a MOBO?
Is there any benchmark freeware?

I've posted many hyperlink threads to support my claims. As far as the 90fps that's per the Video Card Stability Test I'd located, and YES, it's FREE... download it and see how it says your system benchmarks! Apparently the X1600 is a late 2005-vintage as is the AGP video interface your mobo (motherboard, or system board) uses... I have one of those Socket-A's myself in my late 2003-vintage AMD 2500+ Barton core system with the ATi AIW 9600xt... it does alright on the old MP 0.2.3.0 but I never said it would run the more graphics-intense MP 1.0.2
Regardless of which MP version you used to record a TV show, it should be a video file which when decoded/displayed will call on your codecs... The (format of the) recorded files should be exactly the same and should playback smoothly outside of MP. Why some are not may be a function of your broadcast format - in the US we are now (as of June 12, 2009) 100% ATSC Off-The Air (OTA) which requires only about 2% CPU to stream to a Hard Disc Drive (HDD). If your system is analog, it may be having to encode the broadcast (realtime) to your HDD which could explain why some stations do well while others don't. And, it could be a reception issue when it was being recorded... check your log files to see if you are still having reception issues.
If it were me I'd replace the entire system. In today's market you can buy a new mobo with iGPU, a decent CPU and 2x1 GB RAM for less than you paid for that X1600 by itself in 2005! Upgrading either your CPU or GPU is very questionable (in availability and technology level) and expensive. What I did see in your TaskManager was heavy svchost.exe CPU usage. Do an internet search for this as the various occurances do your system tasks... what codecs are you running? Video/audio? Are your files mpeg-2, or .264? WHY would this issue of textures and interlaced video effect your Standard Definition material, unless there in Germany it is an interlaced format? Does your X1600 help with Hardware Acceleration or are you fully s/w and hence CPU bound? Not being from Germany I don't know your broadcast format, whether you're even doing broadcast (you may be doing satellite), or the exact configuration. If you don't want to upgrade then I'd look at playing back with an older version of MP (1.0.0.0) or configure MP to use an external player which does playback without the recent texture issue.
I hope this helps you understand your system better, its age/performance, and some options. Please click on the hypertext links when reading my posts. There is a wealth of information in them...
One last thing, was your 6200 A-LE on-board or an AGP card? Did you load the ATi drivers for your X1600? What version -- some report issues with the later ATi drivers although I can't say whether the older X1600 would be concerned... but check the posts on here about which is a non-buggy ATi driver version. IF the 6200 A-LE is on-board, did you disable it in the BIOS? Surely you're not trying to have two cards running simultaneously!
