Am I correct to assume that xvmc's iMotion and iDCT only work with mpeg2 files? So on files transcoded from mpeg2 to mpeg4 I loose the ability to have xvmc help with rendering?<br><br>I have definately observed this as any transcoded mpeg4 shows don't use xmvc. But then again why are there options to enable iDCT and iMotion on the transcoding menu in mythtv?
<br><br>If this is true it makes a case against transcoding files in such a way (converting to mpeg4).<br><br>Thanks.<br>
