I've been happily using Mythtv for a couple years, and a few months ago
I upgraded my tuner cards from analog to digital/ATSC in preparation
for the DTV switchover in the US. All is working fine in that regard,
but I did discover that my front end systems don't quite have the power
to do the playback on all channels (some broadcasts seem to be more
cpu-intensive than others). "top" reports that CPU usage is pegged at
100% during playback.<br>
<br>So I'm in the market for an upgrade, and I was curious if anyone
had some recommendations on what features I should look for. More
specifically:<br><br>- does the decoding benefit from dual cores or would I be better off with a single core at a higher clock rate?<br>
- any benefit from a larger cache (is it worthwhile to go for 1MB of L2)?<br><br>Thanks
in advance for suggestions and I apologize if this question has been
asked before (my brief search through the archives didn't find anything
along this line).<br><font color="#888888">
