After a lot of searching I found a couple of other threads on my problem. The latest being:
[unable to post URL but thread is named "FireWire play out is now broken on my Comcast DCT"]
Seems many of you have had this problem longer than I [in the Sacramento Comcast area].
raj provided the following work around which I plan to try today.
[indent]I found a work around! I will give you the basic thing here, and I'll post a tutorial on my blog tomorrow. These instructions are for my Mac, so YMMV.
With the firewire unplugged from your computer, start up the program on your DVR, and pause it a good bit before where you want to start recording.
Plug in the Firewire to your comp, and open your recording software, on my Mac I used AVCVideoCap from the Firewire SDK. You will notice when you plugged in the Firewire, the program started playing on your TV, even though it will still have the "pause" icon on your screen. This is good.
Actually start the recording. When you do this, the picture will pause again on your TV. At this point, press play on your remote to "unpause" your DVR. This process somehow makes the DVR now output audio AND video over the firewire.
