Vista EVR 25fps 50 fps

[Pascal]

Recently installed vista home premium, because I couldn't wait. Seems all is working fine, but... having some issues with the mpeg-2 interlacing.

I use the EVR, because with VMR9 and exlusive directx, MP minimise whenever another application is in focus. I have a dual screen setup, so that is not what we want (Read in another thread someone having this issue too). Using EVR or VMR9 + excl dx are the only modes that do not have tearing.

When I use the nvidia codec in EVR, the fps is limited to 25fps. So fast movements don't look nice. I checked in VMR9 + exclusive directx and fps are 50fps. I discovered using the Microsoft MPEG-2 Video Decoder that fps are in EVR 50 fps (checking with '!'). However this seems to be software decoding, because other application activity causes frame dropping. Also channel changing is sometimes slow and skipping is slow too. I remember from my XPSP2 setup, that this didn't happen for sure.

Anyone having EVR and HW interlacing (50 fps) active? Or suggestion of what to try?

Cyberlink PowerDVD7.3, Nvidia purevideo is not correctly working with Vista\EVR with hardware support, had a couple of other issues with the Nvidia codec as well which were not apparant until i switched to Vista, so stopped using it.

there is a current post about Nvidia Purevideo labelled BUG

Hi,
I tested Vista on my htpc a couple of weeks ago & with nvidia based cards i had no go(ATI based worked fine), so now i'm waiting for better drivers from nvidia before next try......

Hi Ray,

Thanks for your (quick) advice. Just installed the powerdvd 7.3 but still no luck with the framerate. Using '!' shows me 25 fps. Do you know which of the codec I should use?

Do you have it working with hw and 50 fps?

thanks,

Pascal

Sadly 25fps is all I see.

Picture is really smooth on MCE but not in MP .

[Pascal]

Microsoft MPEG-2 is the one that gives me 50fps, but like I said it is software based, so sensitive on cpu activity...

well, this could possible be the outcome of hardware deinterlacing combined with Inverse Telecine. i.e. the original source of what you are watching was recorded with 25 fps, so this is what you get to see. in this case (if you got your TV set up to a multiple of 25Hz) it should be smooth as silk too. 25 fps isn't necessarily bad in that case.

[Pascal]

Interesting info,

Inverse Telecine sounds interesting. I thought I have a nvidia 7300 GT with an analogue tv (PAL). In vista I can only put the driver in 25Hz interlaced format. My tv card captures in 25Hz and I believe that would be progressive. Is inverse telecine also used with PAL? I thought only de-interlacing is necessary.

Getting a little bit confused here...

Anyway I just tried the inverse telecine option, but the picture doesn't look different. Specially eurosport shows that it is not as smooth as in XP (or normal tv).

Thanks anyway,

Pascal

Hi ppl,
I'm experiencing the same situation. When I'm using Nvidia purevideo decoder I only get 25fps (blend de-interlacing) on video that should be bob deinterlaced. Once again it works fine if I use a software decoder but id prefer not to. Does anyone know how to change the video settings in Vista? Everything seems to be hidden away. Most of the Nvidia tv output settings have disappeared from the winxp ones.

Hi,

I believe that the MS decoder uses hardware acceleration. Read it somewhere in these posts:

http://forum.doom9.org/showthread.php?t=125835&page=3

If it is true, than it means to me the stuttering is not caused by hw acceleration, but something else??

Still if someone has 50 fps smoothly running in vista, i would like to hear the setup. Which gfx card, codecs, etc.

Thanks in advance!
