For whatever it's worth, HD content plays just fine for me with XvMC turned on as long as there's no OSD and as long as I've paused for a few seconds to create a bit of a buffer. What's unacceptable is that whenever XvMC is turned on and there's any OSD overlayed on any content -- HD or standard def -- everything gets stuttery and MythTV becomes difficult to control.
<br><br>Anyway, it's disappointing to hear that you're still experiencing OSD/XvMC problems even after upgrading to 0.19. Looks like it's option 1 for me after all.<br><br><div><span class="gmail_quote">On 2/14/06, <b class="gmail_sendername">
