I ended up backing up to 6836 to try the Cuy patches for ATSC scanning.  
To be safe I started with a new mysql database.

I'm now getting the CPU load I expect.  I'll move forward to the latest 
again soon to see if it was the database causing my performance problems.

I haven't seen the recording problems you mentioned, but I've only got 1 
pcHDTV HD-3000.
