How old is the PTVNet ISO? If it like a month old it should support the USB200M. I'm using two of them now.

 If you installed for USB 2.0 drivers, then the  Belkin is not going to work. Do you have a serial cable for the TiVo? If you do, connect using Hyperterm (or some other terminal emulator) and you can switch the 2.0 drivers for 1.0 drivers (I forget the command, but you can find it here easy enough). I had to do this on my other TiVo and my FD5050 works just fine.

If you connect to the router, does it assign an IP to the TiVo using DHCP?

Does the 'ipconfi' command work on the TiVos? I haven't tried. If it does you can see if you are getting an IP address on the TIVo.

If you hook up the serial cable between the DSR704 and the computers, just hit the 'Enter' key and you get a BASH prompt.

This Thread tells youwhat to type into the BASH to swap the USB drivers to the 1.0 version.
