    Question ati 4850 choppy video with restricted drivers

    Hi all

    First of all, congrats on a VERY nice looking and functional distro, I was origonally using SuSE/Debian and I think I've found my new OS.

    I have a radeon HD 4850 and an X-Fi extreme music card (not the best combination to start with, I know ) Sound is working fine with the exception of missing 5.1 but video is another story...

    I enabled the restricted driver for the video but was getting a choppy display i.e. when moving a window around with Compiz installed or watching a movie. Initially when going fullscreen it would freeze the whole system but that issue is now fixed by adding 'no-xv' to gstreamer properties. I tried downloading the newest binaries from, and enabling vertical sync but still no luck, videos are unwatchable. Next step is disabling compiz I suppose, although that's a bit of a shame.

    Any help would be very much appreciated as I've spent about 2 hours googling and experimenting. Would hate to go back to Windows 7 but need this working as a multimedia system as it's hooked up to the plasma in the front room.

    AMD's drivers are still pretty spotty performance for compiz, also with making your CPU do the video work.

    Although I just read about a 9.6 revision of the catalyst driver here with updates for playback, dual monitor etc. Im going to check it out myself.

    I have a 4850, If still trouble I would suggest using the open source drivers for the time being (no compiz but 3D support is on the horizon) and great accelerated playback. radeon/radeonhd (xserver-xorg-video-ati or -radeon)
