How to use EVR with XP

[ydekmekji]

I have XP. I have SAF installed and EVR is working--except in saved recordings, EVR lags a little bit. So EVR works just fine in Live TV, but not in playing back I'm assuming there is a way to fix that? I hope... Thoughts anyone?

Hi.
You should not mix DxVA 2.0 EVR renderer (vista/Win7) with DxVA 1.0 OS (WinXP).
For example you wont be able to use DxVA for h.264/AVC.

Thanks for the response but i don't know what that means... how am i mixing? How do i change? sorry...

Basically what hoborg is saying is. EVR under XP will not allow for DxVA (hardware accellerated video, where the video card does the work not the processor) and VRM9 does allow hardware acceleration under XP which can greatly improve video performance depending on graphics card. This is helpful when you have a less powerful processor and a high powered video card, ie the atom processor and ion graphics card combination. in this case DxVA is needed for any kind of smooth playback. It will be clear you have issues if your playback is stuttery

Although i am not sure this is the route of your problem as you do get smooth playback in certain areas, but i would recommend that you switch to VRM9 rendere in xp and try a DxVA compatible decoder to see if it helps.

Alternatively you can try other decoders to see if they change performace

Thanks imagn... i'll stick to VMR9... but i'm still at a loss why EVR would work perfectly fine for live tv but not for saved recordings... seems to me that live tv would be harder to render than saved recordings

maybe it wasnt even using evr for livetv

no gain using evr on xp
fse is still the best on xp, downside is you cant do anything else on pc while using that

[ydekmekji]

nah... i can tell the difference. watching sports on livetv using evr vs vmr9 was a much better quality

[stustunz]

what decoder are you using now?

[ydekmekji]

These are my settings:

Audio Renderer: Default (Recommended)
MPEG2: ffdshow video decoder
h.264: divx h.264 decoder
mpeg1 audio: Dscaler audio decoder
ac3 audio: ffdshow audio decoder
e-ac3 audio: ffdshow aduio decoder
aac audio: divx aac decoder
he-aac audio: divx aac decoder

ffdshow was always laggy for me

i use power dvd8 video
and nvidia for audio

if i were you and wanted to keep trying evr try different audio decoder

when you say laggy
does the audio lag or is it jumpy
