[SOLVED] BSPlayer 2.24 problems after new GPU driver install

[estugarda]

Since I installed NVIDIA 163.69 driver few days ago, I noticed that there is no hardware acceleration (pixels are visible, video is not so smooth as before) in BSplayer 2.24 build954 (when rendering is set to "Internal renderer Direct Draw surface" - which was the only 100% working solution for me on Vistax64, and which worked fine until 163.69). In Media Player acceleration works fine though, but it doesn't play some videos. I never used it much so I can't say if this was so before 163.69.

Interesting thing is that my DVB-S TV app has "Generic video renderer" as Video Render Mode, and there it works great. Acceleration is working there.

Before this new NVIDIA 163.69 driver I had 162.22 driver and it worked great for few months - since I had Vista x64. With the same hardware and codecs as I have now, none of these problems did show.
My first idea was to go back to 162.22 when I discovered the problems, and so I did, but pixels were still visible in BSplayer. Last night Windows has updated GPU driver back to 163.69, and the problem is still persistent.

What can I do?
Thank you in advance...
