Problem withhardware acceleration

[bakerpr]

On sd channels using both nvidia or cyberlink decoders I have problem with distorted bottom half on the picture.

Turn off HW acceleration and distortion goes but picture lacks fluidity.

 

Edit: This problem is generally with overlay renderer as I can get a full picture with vrm7 with the HT fix enabled.

Most likely a problem with your graphics hardware, please contact the hardware manufacturer.

Thanks, the problem appears to have been with the graphics driver I was using which I have been reluctant to update since 84.43beta has given the best picture for H264 broadcasts.

I have suffered of the same problem (distortion of the lower portion of the screen) and seen it reported also on a Finnish DVB-forum. In my case VMR7 does not help. (normally I am using Overlay mixer).

 

The problem seems to be always related to Nvidia graphics cards (Different models and different MPEG decoders, in my case Cyberlink).

Here is a summary of problem details

- occurs both on live display and replay of recordings

- playing the recoding with another player does not have the problem

- switching of HW-acceleration removes the problem

- in my case operating system is XP Media Center Edition with latest fixes

- HP Pavillon DV2140 / NVidia Geforce Go 6150 with latest drivers

 

The report in Finnish DVB-forum says that chagning resolution fixes the problem (but not in my case).

In my case however going to display properties/Advanced/Geforce 6150 pane removes the problem (but closing and restarting DVBViewer brings it back).

 

This indeed seems to be Nvidia problem, but as I am already running the latest drivers I do not see any speedy remedy from there. Any suggestions what to do to find a work around?

 

Thanks
