Update:
After removing a timing/irq kernel boot switch, and with the larger
write buffer in Myth, things *seem* much nicer. I'll know once I watch
any of the recordings, especially HD.
One thought I did have, and should have known from the 'old' days of my
youth - I should probably put the OS and swap on an IDE drive, and use
the SATA's purely for storage...
Well, that' for a 'lazy' saturday afternoon
