i know it's bad form to reply my own email but i wanted to give an update to
my time warner firewire situation. after stopping all mythbackends,
deleting all capture cards, and adding them back again, i was once again
able to capture via firewire. i am able to receive all of the hd channels
that are available through time warner except for espn hd. i can also
receive many digital cable channels but i didn't take the time to write down
exactly which ones but i can if someone really wants to know.
a strange thing i noticed is that when i run firewire_tester it fails every
time for p2p and for broadcast, but i can record using test-mpeg2 and
through mythtv. i also noticed that even though mythtv tells me that the
sa4250hdc is not supported by any channel changer, when i change channels in
mythtv, the channel on the cable box is changed but not to the right one. i
didn't get far enough to set up an ir blaster, but i assume once the script
for the ir blaster is in place, mythtv will no longer try to change the
channel via firewire for the sa4250hdc.
so in the end, i will have to stick with time warner's really awful sa8300
to supplement mythtv. maybe one day we'll have a cable card hd capture
card. many are of the opinion that this will never happen for linux but one
can only hope.
