    I feel frustrated... my ati X1300 can't play a single video without dropping frames.... Opengl output works, but frames are skipped as hell... Hope that the new drivers next month will fix that...

    As I said in the "future" thread... I've tested with the latest build of mplayer, both standalone and with the SMplayer front end. I've tried all of the TexturedVideo, TexturedVideoSync, Textured2D, TexturedXrender, and BackingStore options in xorg.conf. No change with any of the above.

    Xv is simply not running yet on the R5xx parts. Hopefully the next revision of fglrx will include support for Xv video acceleration on these cards.

    Big news! As of 2/24, the xf86-video-ati dev team have just implemented TexturedVideo support for the R100, R200, R300, R400, R500, and RS600 (including RS690) cards!

    This should enable Xv acceleration on the newer cards, like mine. Great news.

    Default big difference

    Wow, doesn't seem like there should be a 7-8 times difference in rendering speed.

    LOL @ ATI/AMD... Open drivers already support Xv accel perfectly... Shame on you guys... I can only say two words: CODE MERGING!

    Come on linzerd... don't be too harsh. They're working on full 3D acceleration, of which TexturedVideo is only a portion.

    Also, I wouldn't be too quick to say that the open drivers support Xv "perfectly"... it is certainly not that yet, and the degree to which the feature implementation becomes robust and efficient remains to be seen.
