The IEEE1394 port on the RNG110 is enabled, but it's operation is not correct. PAT and PMT is missing and there's a huge amount of stuffing packets on PID 0x1fff. No D-VHS box of any kind can ever work with an RNG110.
However, the video and audio streams are present. With some software trickery, I was able to capture a workable Transport Stream for both MPEG-2 and H.264 channels.
If anyone knows what's going on with my RNG200 DVR from Comcast, it might be you, Ron. I have an old DCX-3401 that I sometimes record stuff to my PC via the firewire port. I also do the same with my newer Comcast box --- an RNG200 (aka DCX-3501). So they are both Motorola critters. Now that most of the channels have been switched to H.264, I have noticed a huge difference in the file sizes when I record H.264 content from the RNG200, versus the DCX-3401.
For example, if I record a 2-hour movie from the Hallmark channel for my stepdaughter, using the DCX-3401, the file is a little over 3GB in size. If I record the same movie, same channel, using the RNG200 (DCX-3501), the file size is over 20GB!!! Usually about 23GB, actually. Both files are quite playable with the VLC Player app.
Ron, you say you have an RNG110 and you noticed "a huge amount of stuffing packets on PID 0x1fff" in the stream you captured to a PC. I am not sophisticated enough to look inside packets (although I do have an IT background), but do you think that what you observed might be what's going on with my gargantuan file sizes from the RNG200?
