How to disable video playback acceleration in win 7
I have notebook HP Probook 4730s and have problems playing flash and wmv videos. Both look like they are not antialiased in fullscreen, so it looks terrible. The gfx adapter is radeon hd6490m which hardware accelerates wmv and flash (youtube) videos. I've already tried three different ati drivers and everywhere it's the same. The other video formats play fine. So my question is how to disable video playback acceleration on ati card, or how to disable it in windows 7, because I've already tried everything and really cannot solve this issue. I have windows 7 home premium 64 bit. Thanks in advance to all for response.
edit: so I manually switched to intel hd gfx adapter and the problem didn't solve, so now i really don't know what it could be. Just wmv and flash videos playback is corrupted, i have no idea what now....
