Comcast/Motorola DVR and Ethernet connection?

Archived from groups: alt.video.satellite.4dtv (More info?)

Just recently I have had a Motorola DVR box from Comcast installed at
my home. It replaced my older HDTV set top box. With the old cable
box, I had been told the DVI output was not enabled. On the new box I
thought I would try it out. On this box it is enabled and works. Then
I started looking at the other inputs/outputs on this box. There is an
Ethernet port, so what the heck, I tried to hook it into my router, to
see it I could access the hard drive via my PC. Well no luck, so far.
I have not even been able to "see" this device on my network. I guess
that's why I'm posting this. Does anyone out there know how to make
this work? In case this would help, I have a linksys router, and a PC
running Windows XP pro. I'm not even sure what I expect to accomplish
by doing this, but thought perhaps I could watch the files from my PC,
or maybe burn them to DVD for long term storage.
