DVD Ripper CUDA for MPEG2 - bug?

[davecuk]

The CUDA implementation significantly slows down the RIP/Encode rate for DVDs. Normally I get between 90-120 fps (depending on source material). With CUDA enabled I get around 56 fps.

In addition CUDA implementation for MPEG2 decoding makes no significant difference in CPU utilisation when copying a DVDon my system 2-3% reducing to just over to 2% with CUDA enabled.

Card NVidea 8800GT, Intel Quad Core (2600), DVD copy and ripping.

Hi davecuk
Did you used the lastest build 8032,and have not any problem in my PC.
Good luck

Yes, I always use the latest builds, it seems that CUDA is slower for me than my CPU when ripping, however much faster when H.264 encoding 200+ fps! Again a little unfortunate though because the output is buggy with glitches etc.. in the final video.

It's not my card because I use it for other video processing/editing work (CUDA enabled editor) and it's fine.

Perhaps this is all fixed in 8.0.4.0 (I have just downloaded)?
