[mythtv-users] High CPU / Lockups. Diagnosis?

[mark]

Also, I am running NVidia 6111 and no XvMC ( I dont think )

Here is a top from the machine just watching live TV.  I dont see which 
process is causing the load.
The load is 1.37 and the main CPU user is X but that is even low.
Very strange:

top - 06:54:06 up 12:28,  4 users,  load average: 1.37, 0.77, 0.69
Tasks:  96 total,   2 running,  94 sleeping,   0 stopped,   0 zombie
Cpu(s): 13.0% us,  4.7% sy,  0.3% ni, 80.7% id,  1.3% wa,  0.0% hi,
