Only one of my four frontends have CPU&#39;s capable of displaying SD video with .21, yet were all able to comfortably display similar video from the same tuner cards with .20.2.&nbsp; I have tried every reasonable setting in the TV playback section and while I&#39;ve been able to improve things, it&#39;s not as good as it was prior to my upgrade.&nbsp; All of my machines can happily display video recorded by myth on VLC, while the internal player struggles to keep up.&nbsp; On my Pentium D system, I saw 7% cpu usage on VLC, while mythfrontend.real used about 24% of the cpu to display the exact same file.&nbsp; On my P4 1.7 ghz frontend, VLC used around 35% cpu, and mythfrontend used about 70% (and experienced minor skipping).&nbsp; Doing similar work on a Mac G4 systems (in this case, a 1.33ghz ibook g4), VLC used about 55%, while Myth used 75%.&nbsp; 
 So it seems that on every system I can compare, on two diferent OS&#39;s, Myth needs more CPU to do about the same job as VLC in terms of displaying video.&nbsp; I&#39;m not the most experienced Linux user, and compiling from source would be quite a challenge for me (also, I&#39;d have to compile from source on two different environments, Mac OS X and Ubuntu).&nbsp; I&#39;d really like to stick with the packaged releases, but assuming I don&#39;t replace/upgrade my 4 frontends, do I have any hope of the CPU penalty of using myth improving?&nbsp;&nbsp; 
 I&#39;m seriously considering downgrading to .20.2 again, since it seemed to fit my hardware better.&nbsp; If I do &quot;downgrade&quot; what problems can I expect?&nbsp; I did backup my database prior to the &quot;upgrade&quot; but I&#39;ve never actually had to restore from a backup.&nbsp; I realize that any recordings made after the upgrade will be &quot;lost&quot; (they will be present on my system, but not listed, since they will not be represented in the database backup file).&nbsp; 
 I don&#39;t want to come across as a whiner, and I hope I don&#39;t sound ungrateful.&nbsp; I really appreciate all the work that goes into Myth, and I really like using it.&nbsp; I will eventually have to replace all my hardware when I eventually make the move to HD, but that&#39;s a ways off in the future.&nbsp; 
 I&#39;d really like to stay with .21 if there is to be a solution to my problems described above, but I&#39;m not going to put up with poor performance just so I can use the latest software. Thanks for reading, any tips or pointers would be appreciated.&nbsp;
