</div>I am not an expert but I think I read that you have to upgrade your<br>
backend as well. It sounds from your post that you just upgraded your<br>
frontend.<br>

</blockquote></div><br></div>Thanks for all the input. I do not have the time to describe every detail of my setup, so I'm sorry if my first attempt has misled people on the list. I'll take another stab at it here:<br>
<br><br><br> I have a myth system consisting of a main backend and several frontends. My setup worked well, and I should have known better than to mess with it, but I have a general compulsion to update and upgrade software to the "latest and greatest" whenever possible (I'm probably not alone in that compulsion). On all of my machines, regardless of the distro installed, I run binaries from the package manager, from the appropriate repositories for each disro. On my Ubuntu 7.10 systems, I enabled the "Gutsy-Backports" repository, which incluldes mythtv version .21. <br>
<br>So anyway, I had a .21 backend and 3 .21 frontends all working quite harmoniously. The backend, and one frontend were running Ubuntu 7.10, one is running Ubuntu 8.04, and one is running Debian etch. Since my one machine was running well on 8.04, and since the official release had come, I figured it was safe to update my 7.10 backend and 7.10 frontend. Without changing a single myth-specific setting, I went into the update manager, and clicked on "upgrade distribution to 8.04" or whatever it says. Half an hour later, I had my frontend upgraded to 8.04, and an hour after that, I had my backend upgraded (I did the upgrade on the frontend first to make sure the upgrade process was still stable...I had previously upgraded my other frontend from 7.10 to 8.04 without incident when the beta 5 release came out) When all was finished, my backend seemed to work fine, and I had no trouble accessing it as I always had from two of my three frontends. <br>
<br>My "main" frontend" the one that I had just upgraded from 7.10, did not work so well. This machine would connect to the backend, and appear to be ready to work, and could display video (using the Internal player) but could not display recordings or live tv. I strongly believe that my problem has nothing to do with the specific
playback settings. It is not an issue of changing my deinterlacer, or
anything of that nature. It seems to be a problem related to the
connection via the network, or loading streams, or something else.
Watching the lights on the switch that connects my main frontend to the
backend, I can see the lights blink like it's trying to load the video
stream, while I see a black screen on my TV. Then, about 20 seconds
(It normally takes 3-5 seconds for live TV to appear on my TV after I
click the button) the blinking on my switch stops, and I'm left with a
blank screen. I hit escape to go back to the menu, and nothing
happens. At this point, my choices are hit "CTRL+ALT+Backspace" to
restart x (and mythfrontend.real) or to hit "CTRL+ALT+F1" to go in and
kill it manually. Otherwise, it sits there for displaying a black
screen with no other noticable activity. I messed with everything I could think of, and ultimately decided there must have been a problem with the upgrade, so I reinstalled the packages through synaptic. Once I was finished with this, nothing changed. So I figured there must have been a problem with somethign else, and decided it would be quickest to just download a fresh copy of mythbuntu 8.04, and do a fresh install on the frontend. So I go through all these steps, and when I was finished, the performance was exactly the same. I could watch video, but nothing that originated from my tuners. So, I decided I needed a quick fix, so I poped in my mythbuntu 7.10 disc, re-reinstalled, and updated (to get back to the configurarion I had before I started with any of this) and it worked fine. <br>
<br>Others seem to have similar problmes, so please feel free to offer suggestions for that reason, but my spefic problem has been solved (or at least worked around). <br><br>Thanks again,<br><font color="#888888"><br>Josh<br>

I had xvmc setup and working under 7.10 (on my FX5200 card), but I'm not sure if that changed after the upgrade. The reason I mention this, is my videos were mpeg-4 files, but both the recordings (made on my PVR-500's and my PVR 250) are mpeg-2 files. Perhaps I'll try the upgrade again and check this next time around. <br>
