Set the DCT connection setting to Broadcast and 200 or 400mbps. power
down the computer and the cable box and repower both, this should
solve the issue. as well, if channel tuning doesn't work use 6200ch
(in the contrib folder) for channel changing and try the "new" method
(theres a switch to enable it).

This is a firewire kernel driver problem. Some firewire chipsets
aren't as bad as others, but its a problem with the kernel and
partially Myth,  both of which are being worked on.
