OK, I finally figured out the routine to get my air2pc (v1) configured
in myth last night. using that machine as a frontend/backend
worked fine-I could record, watch live, watch recorded. The
backend is an athlon XP 3200/SiS 741 chipset mobo with an nvidia
5600. This pc was entirely configured from ATRPMS packages back
in august (long project-short on time)<br>
<br>
So I moved over to my frontend (to see if the HD stream was going to
choke the network). The frontend is a VIA/ASUS based Compaq with
a socket A Sempron 3000/512mb mem. Video is an ATI 9600 with the
fglrx driver from <a href="http://Livna.org">Livna.org</a>. This PC has been configured from
ATRPMS packages as well. Allthough this version of myth seems to
be updated from the one installed on the backend.<br>
<br>
Playback of material across the network that had been previously
recorded on the backend using a bttv card worked fine. Xv
accellerated playback was checked in the frontend config (and it
works-checked proc. util with and w/o xvmc checked in myth).
Playback of manual captures from the air2pc (cat) also worked for the
most part (using xine or mplayer from the commandline).<br>
<br>
When I try to open a recorded HD show or live tv, I get a failed to
initialize comment and myth goes back to the mail menu. terminal
Output using -v playback, audio and some others is below.<br>

So, does anyone have any ideas? When I play back the old SD
recordings from the bttv card, using the same verbose output it
connects to Xv port 67. But nothing for HD. This ATI driver
is pretty new (10/14?), so I suppose it could be a flaw there. If
I disable Xvmc in mythfrontend, the HD stuff will playback, but very
choppy/slow with 95% processor utilization.<br>
<br>
I'm thinking that another $40-50 on a Nvidia 5200-5600 would be a
decent investment-but feel like something is broken somewhere and don't
just want to throw new hardware at it. Plus, I have another box
slated to become a frontend (currently my big Dell Gen 3 MCE box) that
has an X800SE Radeon. Hate to have to replace that one too.<br>
<br>
Thanks,<br>
