[mythtv-users] Firewire troubles after upgrade. Is test-mepg2 mightier than MythTV?

It looks as though my firewire recording problem has nothing to do
with my firewire card.
I bought a new Agere firewire PCI card. (Which other Myth users have
(This card can be found at BestBuy sold as "Dynex")
I disabled my on-board firewire controller in the BIOS.
My system now reports:
root at myth:/home/myth# lspci | grep 1394
01:0a.0 FireWire (IEEE 1394): Agere Systems FW322/323 (rev 61)
The new card works exactly like my original one:
- firewire_tester still works perfectly
- test-mpeg2 also still works perfectly
- Mythtv still fails
I could find no major differences in my backend log with previous
Next, I wanted to see if Juju was the culprit.
I installed Ubuntu 9.10 x86_64 (By default Ubuntu does not use juju)
With Ubuntu I still see the exactly same results (the test programs
work, but myth fails).
So to recap, I have been able to rule out the following possibilities
as the source of my problem:
- Dual-Buffer mode (my 22A card didn't use dual-mode anyway)
- Firewire card (same results TI card and Agere card)
- Firewire stack (both juju and the old stack give me the same results)
- Distro ( Ubuntu and Fedora face have the same issue )
Firewire capture *did* work with Ubuntu 7.10 and myth. 21
Having reasonably eliminated other possibilities, I'm betting that my
problem lies within a change to Mythtv itself (and not the OS).
Time to dust off gdb...
