start a new thread someone will help you

ps this is not meant to sound harsh just people wont see your problem in here

sub, I don't know if this will help you but I played around with the EVR's "Aspect ratio mode" properties in GraphEdit on XP and got the following results:

MFVideoARMode_None displays the side-squashed image we are experiencing.
MFVideoARMode_PreservePicture displays the video in a proper aspect ratio.
MFVideoARMode_PreservePixel displays the video in a proper aspect ratio.
MFVideoARMode_NonLinearStretch stretches the video to fit the screen.

This was done with a 4:3 video on a 16:9 screen.

he is using vista i think
it worked for me on xp as long as i didnt use cyberlink decoder

i just noticed shining dragon isnt using anamorhphic/raw nvidia does dumb things otherwise

Could you not get the cyberlink decoder working with EVR under XP at all? As mentioned in another thread I had it working fine in graphedit, but just got a light grey screen in GB-PVR itself when trying to use it.

mine was stretched sideways unlike everyone else
i gave up on it as hardware accel wouldnt work
i have 3 analog tuners and 1 digital (soon to be 2 digital)
i cant do without hardware accel so evr is out

cyberlink 7 still doesnt cut it on my machine compared to nvidia (even though it says it uses the nvidia pure video when you look at config within power dvd itself)
dunno if cyberlink ultra is any better but i dont have it so cant try it

GB-PVR always uses the MFVideoARMode_None aspect ratio, just as it does with VMR and Overlay aswell. It then controls the aspect ratio by programmatically using
IMFVideoMixerControl->[SIZE=2]SetStreamOutputRect().

By default MFVideoARMode_None should just fill the screen.[/SIZE]

Hardware acceleration is not possible with EVR under XP since XP doesnt support DVXA2. For this reason EVR is mainly a feature that will be useful to Vista users. That said, I'm sure there are some people running dedicated setups arent concerned whether its using hardware acceleration or not, in which case EVR can still add quite a lot (better colours, smoother playback etc).

I would put myself in that category but as mentioned, despite having EVR functioning in graphedit I just get a grey screen within GB-PVR trying to playback any type of file.

zip and attach the logs and I'll take a look.

I fixed the aspect ratio problem (sort of).

XP users, replace c:\windows\system32\evr.dll with the one in the attached zip file. Vista users can download this updated dll from http://support.microsoft.com/kb/935878/en-us

Close PVRx2 before replacing the dll.

Caveat: Aspect Ratio modes in config.xml with negative values are not accessible. PillarBox is the closest to the 4:3 ratio. I'm sure that you can edit the values to find the right aspect but I stretch to full screen anyway.

Ah, good find. Hopefully that resolve it for all that had this problem. As far as I could tell from the logs, GB-PVR was doing everything it was supposed to, and it was definitely working on some machines... so I was scratching my head over this.

Correct. It has the same limitation as the Overlay renderer in the past and will not allow any values outside of 0,0,1,1 in the aspect ratio. GB-PVR will automatically skip these settings.

Not having these negative aspect ratios is not major issue though, since there is only a couple of 'not so common' scenarios that require them.
