I finally enabled QE/CI on my X1650 Pro. I need some advice as to how to smoothen out my DVD playback, it is a bit choppy.

@Ali C.That could be due to the drivers you are using. Is all video playback choppy? Or just DVDs? The answer may narrow out the cause.

Here is my Xbench results for my video card hope this helps in some way:

MY video is fine, accept for DVD playback as far as I can tell. I haven't tried DivX or any other format yet. I will try PLEX Media Center and see if it clears up. The DVD playback is not so much choppy, but stutters, that is best way I can explain it.

Field Note #2 @xlucian 2009-08-02

i have an ati x1600 pro silent and managed to install a retail leo and after enabling QE/CI video worked like sht…the best solution is to use PLEX media center for Mac OS X…now i run smooth divx and [email protected]'t try yet 1080p. on iatkos v7 and on my first attemps to install retail leo when i've installed the latest version of plex...0.8.1 ...i only had sound...to not have this problem install first 0.7.15..make it work and then update

Field Note #3 @xlucian 2009-08-02

plex has its own dvd player. try it.i have also win 7 x64 and with plex videos runs as good aas on win

Field Note #4 @timcharper 2011-05-20

I have had stuttering DVD / VOB playback in VLC, while divx / h.264 / any format playable by quicktime would play uber smooth. Turned out that VLC 1.1.9 was the culprit. Downgrading to 1.0.5 made the video playback much smoother.

I couldn't get PLEX to play DVDs, maybe there is some steps I need to work through to install DECSS or something...
