Good morning all,<br><br>I just updated my Mythtv system to .21 (from the Ubuntu Gutsy Backports repository) and I'm having mixed results. On one of my frontends, most everything seems to work, but graphics on the screen are "shaky" in some cases. Specifically, when watching news shows, the on-screen text and graphics look like the edges are moving up and down a few pixels. It seems to be independent of the color, and display (this is on a dual head system, and I switched monitors to check that). This is running on Ubuntu 7.10 i386, Pentium D 3.0ghz, nVidia GeForce 7900GT, 3.0GB DDR2 667mhz. This machine does not use XVMC.<br>
<br>On my other frontend, I'm having a different problem. On this machine, I'm able to watch videos just like I could before (using the Internal Player) but Live TV and recordings peg my processor and everything slows to a crawl. Audio skips, and frames are dropped. This machine runs Mythbuntu P4 1.7ghz, 1.25gb DDR ram, nVidia FX5200 and runs as a dedicated front end. I have it set to use XVMC.<br>
<br>I'm recording SD Analog Cable from 2 PVR-500's and 1 PVR-250. Connection is via 100mbit LAN. <br><br>Both machines worked well under MythTV .20.2, and I have not changed any configuration files. I'm running the latest nVidia drivers from the Ubuntu Repositories (which I know have issues in some cases, but nothing to indicate these problems as far as I know). Everything worked well before the update (well, there were occasional frontend crashes, etc. but it worked well enough) and all I did was enable the Gutsy Backport repositories and allowed the machines to update themselves. I had to manually upgrade the video plugin, since it replaces the DVD plugin (it didn't do that automatically for me). Otherwise, I don't see where I could have specifically made a change to cause these problems. <br>
<br>I recalled seeing a thread a few weeks ago about high CPU loads, but the end of that concluded with installing the latest SVN build, which I would assume the .21 release would include any benefits included there. <br>
<br>I guess that got a little long....sorry if that's too much detail. Any help would be appreciated. <br><br>- Josh<br>
