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