I know I'm late weighing in on this thread. I've been busy with other<br>
things.<br>
<br>
I'm running an Athlon64 3200+, I think it's 2.0 GHz. It is underclocked<br>
(because I have some freakishly sensitive memory).<br>
<br>
I get an extremely watchable system, all the channels work visibly<br>
flawlessly... except TV3 which stutters. This includes the Kordia HD<br>
loop which was also working flawlessly. However, major caveats:<br>
1) I'm not using MythTV, I'm using mplayer-svn<br>
2) I'm using "-fs -vo xv -mc 5 -vf pp=fd -vfm ffmpeg -lavdopts<br>
skiploopfilter=all:fast -framedrop" ... so it's probably not perfect I<br>
just cannot see the difference.<br>
3) When initially tuning a channel, mplayer has syncing-up issues,<br>
sometimes jams up and crashes... I can mostly avoid these with a quick<br>
pause and unpause.<br>
4) mplayer still often crashes in decode_audio, but only when initially<br>
getting the video up and running.<br>
<br>
With MythTV, including Paul Kendall's modified version, all the channels<br>
stutter (run 1 second, pause 1 second). So I'm not using MythTV at the<br>
moment.<br>
<br>
Point being... the H.264 decompression can be run fast enough on this<br>
slower hardware.. under the right conditions. The additional overhead<br>
of recording to disk while decoding... well that's probably what bogs<br>
things down.<br>
<br>
I am using gentoo (preempt) so everything is compiled and optimised for<br>
my processor. Thus, it is a bit faster than pre-built systems like<br>
Mythbuntu.<br>
