if i update to a current svn build and the playback becomes choppy, can i downgrade to a build which was working satifsactory?

save out the current one (manually) by moving it.

Applications/XBMC.app is the correct path Wink

when i am watching hd content on the crystalhd enabled atv it works like a charm.

after some minutes it starts lagging like hell. atv cpu is at around 20% load.

I'm seeing the same issue as Andy on r27265. Playback is excellent for a good 10 minutes or so then it'll get choppy for a bit and then start playing good again. I'm using passthrough digital audio, so no audio decode to slow it down. I also see the same 'SetDropState' message in the logs.

I'm hoping to get to the point that we can watch 720p mkv videos flawlessly Smile
Thanks for all the support.

I think we just need to continue to be patient. This is a known issue and as Davilla has said, his time to work on this is limited. This weekend alone there's been 7 commits to SVN surrounding CrystalHD support.

Give the guy some time to get things sorted Wink

Just a side note:
You can always rollback to a revision that works perfectly with 720p. Yesterday I did an update to latest SVN version compiled, then bumped into the same issue as reported here for the ATV.

TeknoJnky did an excellent job with revision installer here: http://forum.xbmc.org/showthread.php?tid...ght=script

Just pick rev26651. Life is good again Wink

... so still 3 times better experience than with recent svn.
So just wait and hope chief Davilla will fix the recent bug soon.
