Hi all,<br>I'm running 0.25-fixes on Mythbuntu 12.04 x64, and am using an Ivy Bridge (3750K) CPU in an attempt to get VAAPI playback. <br><br>Right now, when I play back a recording with VAAPI (no deinterlacing set) the frontend gives me the usual black screen with "Please wait...", but instead of the recording starting I get about a half-second of audio; the screen goes black, then back to the 'Please wait' screen - and this repeats 4-5 times. After that, the machine freezes completely, and I have to hard-boot it. If I'm lucky, I can press escape during the "Please wait" cycle and get back to the Myth menus. <br>

<br>I've seen references to environment variables like LIBVA_DRIVERS_PATH but I don't have these set; do I need these?<br><br>I assume the next request is to ask for a backtrace, but from my reading this requires something to actually crash, right? From what I can tell, I'm not getting a crash, I'm getting a freeze (or a recovery back into the frontend menus). I'm more than happy to be wrong, and to put whatever effort needed into debugging. I ran mythfrontend-real > mythdebug.log, contents of which are here:<br>
