70% CPU (down from 98%) useage is extrememly high, i doubt you are using dxva properly. If i watch 1080P movie i have around 0-2% max cpu useage in MPC-HC and around 5-10% in MP. This is using the onboard HD3200 that you are knocking.

Details, details... the 70/98% you're speaking of is the now defunked HD-DVD format, not .264 and YES, it took ALL my system could muster before my upgrade. How do you get an old HD-DVD to play in MPC-HC?
When you say you watch 1080p movie, what format is that? As you may have read on this other thread, I also found offloading .264 to the GPU (e.g. Hardware Accel ON) using the MPV .264 codec was possible with my new card.
I'm not knocking your HD3200... I wasn't knocking the 7050PV I have on-board, just surprised to find it's now underpowered to display 1080i given the developers new 'texture' philosophy... You were too but this thread is not focusing on .264 decoding... although, I suspect you may be because the clip you posted is .264 whereas the broadcast format in the USA is an ATSC mpeg-2 stream.
It wasn't until I bought this new card and located the Video Stability Test that I even gave a thought to fps throughput, but after realizing there are several iGPUs with similarly low (20~25) fps as my 7050PV I thought quoting those on here would help folks realize just how slow 12-18 months old systems are in today's technology. Please, I'm NO GAMER... fps is not something I want to open a big discussion on... I just want my MP to keep on truckin' like it has for years... you can't push a rope and you can't force these developers to abandon their methodology... you can either spend $25-40 to alleviate the dropped frames/judder, revert back to MP 1.0 or earlier, use an external player, or find another front-end all together. I was trying to explain that a side effect of the new video card is my system is all the more powerful for future "improvements" and showing better performance handling some old formats (e.g. HD-DVD).
BTW, I'm REALLY happy with how well MP 1.0.2 runs! Sure, there are a few 'features' that aren't working but overall it does a great job recording TV shows, playing DVDs, files (.mkv, .iso, .m4v), playing Recorded-TV, skipping, FF/RW... is it any better than MP 0.2.3.0 is a function of progress! Back then we used the .dvr-ms container but that's no longer popular... I only use the SchedulesDirect plug-in, so all the talk and integration for the many plug-ins is outside my scope... I don't consider them as I'm focused on the base application running right (for my purposes).

The only problem here is that IMO nVidia graphics cards suck for HTPC use if you want to watch HD-DVD's or Blu-rays and maintain proper audio. Their audio over HDMI solution is a total joke and thats if you can even make it work. The only real nVidia HDMI solution is to use an 8200+ IGP motherboard and I'm not about to spring for that and have to reinstall everything in the process.
I have a silent ATI 4550 that can play full resolution Blu-ray (ArcSoft TMT) with lossless 7.1 audio without so much as a hiccup. So why can't MediaPortal manage to play a crappy low bitrate 1080i60 stream correctly without some kind of GPU powerhouse?
Bitrate doesn't have anything to do with this (as video decoding itself is done on the VPU on GPU). Things that matter are:
1) Video resolution (texture copy requires lot bandwidth inside GPU)
2) Interlaced content (especially vector & pixel adaptive deinterlacing modes are GPU hungry)
Odd that 4550 doesn't have enough GPU power / fill rate to handle
And remember that when you compare to the other frontends / players, they aren't mixing the 3D graphics with video feed, this is the difference that forces us to use the texture where as other software (like MPC-HC) can just use the surface.
OK, but why is this an issue when playing full-screen - then there is only video content so why can't it switch to using a surface in this case ?
Surely the primary purpose of MP is to play video and audio content - the user interface is just there for control purposes so shouldn't the performance of this be sacrificed (if necessary) to provide the best possible video playback performance on the simplest (= low power) hardware ?

(and no, I don't have the stutter problem - I switched from HD3450 to 9500GT a while ago - but this has turned into an interesting discussion thread
)OSD, menus etc. are still available in fullscreen, so such switching is not possible.
You can always use the external players on the low end PCs (of course you will loose some nice things like OSD and good integration to the frontend).
If you check for example 9500 / 8600 is not that costy anymore, less than 1TB hard drive that you are using for the pirated movies
(not directly directed to you, but most of the MP user base are most likely watching pirated movies, althou its not anything frontend related...).

Well this "discussion" is getting rather offtopic now. There are already some threads covering the hardware "needs" of MP. To make it short: HTPCs are an expensive hobby. If you buy cheap you'll surely regret it at some point. Since MP is meant to be a 100% HTPC frontend there will always be unhappy users who try to get something "for free" to recycle some hardware which was lying around. Easy as that.
I take offense to this. Almost everything in my machine is BRAND new, nothing except for my timeshifting hard drive is recycled. Certainly, nothing was cheap, my wife can attest to that. There is a bug here and it needs to be addressed without belittling the people who are reporting it.

We ALL appreciate the fine product you guys are developing for us! Please don't take our interest as bashing... the fact is it took nearly a month for us to learn there had been any change to the video textures processing beginning with MP 1.0.1. I came to the same conclusion about options for folks when I concluded: you can either spend $25-40 to alleviate the dropped frames/judder, revert back to MP 1.0 or earlier, use an external player, or find another front-end all together.
This IS an interesting first-time departure for MediaPortal... in the past it was a front-end which used registered codecs to display video but with this added fullscreen graphics MP now departs from the basic codec usage and is calling on the VMR9 to do mixing as an enhancement for user interface and functionality of the MediaPortal product itself. This is an important (and first-time) difference because users often use what they know, what they've experienced, as a basis of comparison. That's why we're all interested in this 'discussion.'
Again, THANK YOU all for developing such a robust product and taking time to participate on the forum!
