The 3700 will give you better single-thread performance than the X2 3800. The
3700 (San Diego core, 1 MB L2 cache) is clocked at 2.2 GHz, while the X2 3800
(either Manchester or Windsor core, 512K L2 cache per core) is clocked at 2.0
GHz. If the MPEG-2 decoder used by MythTV is mostly single-threaded (can
someone confirm or deny this?), the larger cache and faster clock speed of the
3700 would be a win.
I've also transcoded some HD movies to MPEG-4 and H.264 to get them to fit on
single DVDs, and they play back smoothly.
