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

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
