Hi Christian.
A patch was very recently committed to MythTV git to fix capture of
MPEG-4 streams via firewire (many of the newer channels on Shaw are
using MPEG-4 now). The patch is set for the 0.28 milestone, but I was
wondering if you could build your current MythTV packages with the
patch in place, so I don't have to wait for 0.28 (or compile my own
MythTV).
Here are the relevant links to the patch and the bug report.

P.S. I can't believe you've been doing this for well over 10 years!
I've been with you for most (if not all) of the 10+ years too! Crazy.
