[mythtv-users] No picture using Firewire on OS X

[Vinnie]

When I try and watch TV, the video is black with no sound. At the top
is the channel # and the time, and at the bottom is says:
"Signal 100% | (L__) Partial Lock"

After a few seconds the following pops up:
"You should have gotten a channel lock by now. You can continue to
wait for a signal, or you can change the channels with Up or Down,
change input's (C), capture cards (Y), etc."

When I change channels in MythTV, my cable box (DCT-6200) correctly
changes channels fine, so something is working, but I still don't get
any video.

Since there aren't any binary backend packages for Intel OS X
available with firewire support, I built MythTV using osx-packager.pl,
which seems to use the current svn source (I ran it this morning).
After configuring the capture card to be type firewire (for my
DCT-6200 cable box), and setting up the rest of the usual video source
and channel stuff, I tried to watch tv.

I wasn't able to use firewire_tester since it won't compile on OS X
for me. The output of trying is below. However, I have tested the
connection with AVCVideoCap in the Firewire SDK and I can record fine
with that.

Has anyone seem this problem or no how to fix it?

Thanks,
  Vinnie
