DB? BD? Bluray Disk? A P8400 is a dual core 2.26GHz processor, which is
a bit on the lower end for Bluray playback. Expect somewhere around
11-12Mbps H264 per core, or closer to 15Mbps if its the rare content
encoded using CAVLC instead of CABAC.

This is a bit odd. Nearly all Bluray content should be multi-sliced,
which means multithreaded decoding. MythTV allows you to adjust the
number of threads to allow, and defaults to two. It likely shouldn't be
stuck on one core.

If you can use the Nouveau driver, that also means you can use the
proprietary nVidia driver, and you should do so.
