<br>This has 2 issues:<br> 1) Sound goes out of sync... a known issue I'm trying "mythcommflag --rebuild" to see if that fixes it<br> 2) Worse still. Now it's a PS the 350 can play it using its hardware decoder. GREAT!
<br> But it ignores the flags that say it's 16:9 and plays it 4:3, suddenly everyone is really tall!!!<br> There's a real dearth of info on the 350 decoder out there...<br><br>I'll try turning off the 350 decoder and see how the transcoded files play thru XV.
