On one of my frontends, most <br>everything seems to work, but graphics on the screen are "shaky" in some <br>cases. Specifically, when watching news shows, the on-screen text and <br>graphics look like the edges are moving up and down a few pixels. It seems <br>to be independent of the color, and display (this is on a dual head system, <br>and I switched monitors to check that). This is running on Ubuntu <br>7.10i386, Pentium D <br>3.0ghz, nVidia GeForce 7900GT, 3.0GB DDR2 667mhz. This machine does not use <br>XVMC. <br><br>On my other frontend, I'm having a different problem. On this machine, I'm <br>able to watch videos just like I could before (using the Internal Player) <br>but Live TV and recordings peg my processor and everything slows to a crawl. <br>Audio skips, and frames are dropped. This machine runs Mythbuntu P4 1.7ghz, <br>1.25gb DDR ram, nVidia FX5200 and runs as a dedicated front end. I have it <br>set to use XVMC. <br><br>I'm recording SD Analog Cable from 2 PVR-500's and 1 PVR-250. Connection is <br>via 100mbit LAN. <br><br>Both machines worked well under MythTV .20.2, and I have not changed any <br>configuration files. I'm running the latest nVidia drivers from the Ubuntu <br>Repositories (which I know have issues in some cases, but nothing to <br>indicate these problems as far as I know). Everything worked well before the <br>update (well, there were occasional frontend crashes, etc. but it worked <br>well enough) and all I did was enable the Gutsy Backport repositories and <br>allowed the machines to update themselves. I had to manually upgrade the <br>video plugin, since it replaces the DVD plugin (it didn't do that <br>automatically for me). Otherwise, I don't see where I could have <br>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 <br>of that concluded with installing the latest SVN build, which I would assume <br>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 <br>would be appreciated. <br><br>- Josh</span></b></font></div></span></blockquote><br></div><div>FWIW, I'm having the same exact "shaky" display issues on my frontend, which is on the second display (seperate x window). I have the gui dimensions and offset hard-set in the apperance settings, yet it drifts almost every time I switch between television and the menu. I'll set it up perfectly so it fills the entire screen w/ little overscan, and a half hour later the offset is randomly 20 or so pixels off. It also flickers a little bit going between the menu and television (desktop visible).</div><div><br class="webkit-block-placeholder"></div><div>I don't know if these are 0.21 related issues, older mythtv issues, or my graphics card. I just got this graphics card and it's my first experience actually using mythtv on my main television.</div><br></body></html>
