1080i material not deinterlacing under 1.0.1.0 (2 Viewers)

[huckster2]

Ok.

Motherboard documentation says.... 1 x PCI Express x16 slot (The PCI Express x16 slot conforms to PCI Express 2.0 standard.)
Video Card is a 240 GT (see here) using Nvidia's latest drivers 195.62.
HDMI to Panasonic Plasma only.
PowerDVD 8 Codec (I will confirm version later)..... 2.2.0725.
With MP 1.0.2, the CPU is around 50% for these 1080i TV broadcasts/recordings. Anything non-interlaced is fine (using the HD3200 or the NVidia, with low CPU). Any 1080i TV recordings played via PowerDVD work fine with low CPU (both HD3200 or 240GT).

So far, everything in MP 1.0.0 is fine. Low CPU. Today's task - 'cos this is all I've been doing every morning since Christmas - is to pull out the NVidia and see if the HD3200 will run ok with MP 1.0.0. If so, then I will stop before I get divorced.

HD3200 works fine (8.12) with 1080i TV live or recorded with MP 1.0.0.

What resolution are you running? (I'm running 1280x720p out my HDMI.)

By the way, MP1.0.2 and HD3200 worked fine at 1280x720 res with 1080i content. I got hit by the problem when I upgraded to a 1080p set and increased resolution to 1920x1080. So the failure to show 1080i content is resolution dependent, so it is possible if you upgrade to a fullhd set, your 9500gt may no longer cut it.

HD3200 works fine (8.12) with 1080i TV live or recorded with MP 1.0.0.

What resolution is your display? 1080 or less?

Currently running 1366x768? - TV says 1080p. I tried lots of resolutions with both cards and MP 1.0.2 - must take a pen and paper with me the next time I fiddle.

Well, you should use the native res of your panel. 768 would be quite common for an older plasma. Anything sold as HD-Ready is likely 768, a full-hd set will have a native res of 1080. Check your TV manual for native res in the specs.

YES, I was also concerned about future upgrades to a 1920x1080p LCD projector myself. To evaluate this I went and changed my PC's output to 1080p and it displays just fine - see attached screenshot! I did see a small CPU increase from 16% to 25% or so at quick glance.

I really am perplexed that this guy's 240 GT isn't fixing the deinterlacing issue - that it doesn't seem to be processing the frames it needs to. I'd like to know how it compares on the Video Card Stability Test I'd mentioned (much) earlier in this thread. I followed up on his mobo and it's newer than mine - accepting AM3, AM2+/AM2 CPUs and PCIe x16 2.0

Doing a quick scan of Panasonic 37" Plasma it seems they have several models using 1024x720 native resolution; although I can't see how the display would effect PC output even if it's scaling the signal on the fly. (That's what I had to do sending 1920x1080 to my 1280x720p Sony AW-15 PJ, above.)

I feel we're missing something... something simple... have you DISABLED the on-board HD3200 (in BIOS) during these tests? Have you confirmed the jitter & dropped frames using the <Shift><1> function within MP? What FPS are you actually achieving in MP? Using VRM9 mode? As I recall, you may not be able to use DXVA on the PDVD codec with the NVidia card... try disabling it within the MP-Config Filters folder and see...

The something simple could be me! It may well be that I had something wrong in the BIOS. I did disable the onboard - I can confirm that, 'cos when I took the Nividia out and restarted, the screen was blank!

No more testing for a while as I've just taken the NVidia card back - they have a 7-day no quibbles policy. As I have MP 1.0.0 running fine with the onboard HD3200 I thought that was the best thing to do. I also found the fan a little noisy. I didn't get many dropped frames - lots of jitter though, and a slow fps ~19 from memory.

Question. I think I've asked this before, but I don't remember if I got the answer I was looking for.

When you tune to a 1080i source such as CBS or NBC broadcasts, what FPS are you getting when doing Shift+!? 30 or 60? I get 30 with no jitter, but Andrew H, it looks like you're getting 60 in your screen shot. What de-interlace method are you using? Is it hardware de-interlacing or software? What codec is it, MPEG2 or H264? What codec are you using to play it--I saw you mentioned MPC I think? I'd really like to get 60 FPS for sports if possible.

Right now I'm using my integrated graphics (GeForce 7050PV) which I KNOW isn't great, but I also know that my CPU usage is not very high when playing back 1080i material.

I'm with Andrew H on this one - if you are getting 50% CPU on interlaced H.264 HD material then something's wrong with the codec/renderer setup. The 9500GT in my system has so far coped with everything I've thrown at it - driving a 1080p display from MP 1.0.2 on Vista32 (195.62 drivers).

I'm doing nothing exceptional other than having installed the N9500GT and disabling in BIOS the on-board 7050PV which you have as well! YES, I'd stated back here (in the first paragraph) that my 60fps dropped to 30 when I upgraded. I use the NVidia codec but the PDVD8/9 work just fine as well. I use "best available" for the interlace as I do not have to cut corners or cheat myself now that the N9500GT is installed. I use hardware DXVA and as you recognize the CBS logo, it's a USA broadcast hence it's a MPEG-2 MP-recorded .ts file and is not .264. I mentioned the MPC for .264 decoding which has nothing to do with MPEG-2 (e.g. USA ATSC TV broadcasts). I'm no videophile - just a man wanting decent playback... I'm really surprised you can even watch 1080i material on the 7050PV - what is your CPU? (Although I don't know whether a high-powered CPU would assist any on this.) Oh, I recall I WAS barely able to watch 1080i material using the DScaler codec as it is a full software codec and 'seemed' to lose fewer frames... but that was only 'til I opted to fork out a few $$ to buy the better video card.

I'm shocked to hear you're getting 30fps on 1080i material with no jitter... how are your dropped frames? How is your viewing? What codec are you running? PLEASE fill in your "My System" in your profile so we can better understand...

Yep, see attachment. I'm getting the 30fps with the 7050PV. No Drops and the only jitter is at the very beginning. I filled in the "My System" section.

Also, I am not using DXVA. I'm wondering if that has something to do with it. Once I enable DXVA, FPS drops slightly below 30 FPS and jitter/drops increase.
