I meant that this specific problem has been fixed so you don't
have to accept your suffering. My firewire recordings are as
reliable as analog recordings.

You're over thinking it.  >= 2.6.23 good. < 2.6.23 no good.
I can assure you that there was a bug and it was fixed. Search
the archives for "Firewire Issues" when the patch went into the
release. My memory failed me. the fix was in the first release
of 2.6.23.

Everyone, including myself, was convinced that their rain dance
fixed the problem. However, it was a kernel bug. Note that in
recent months you don't see as many kill this, unload that, restart
the other thing, check the wind direction, reboot, unplug the
cable for 7sec., reboot into another O/S. unplug the cable box...
