Wow, that's weird. 

How do you have your cable splitters set up? I doubt that's where the
problem lies, but you never know.

Also, do you have any other computers on your network? If so, can they
connect to the network? Or is your computer directly connected to the
cable modem?

If it's directly connected, I'd recommend putting the tv card back in
your computer, then try one of two things:

1) Try hooking a different computer up to the cable modem. Keep your
myth box's tv card hooked up to the cable, but don't hook your myth
box's ethernet port to the cable modem. See if the problem crops up
with this setup. If it does, you have some funky weird black magic
going on in your coax cables.

2) Try using a router. Plug your cable modem into the router, then
plug your computer to the router. If the problem still crops up, try
disconnecting your computer from the network - then connect a
different computer to the network while leaving your myth box's tv
card hooked up to the cable.

Hope that helps,
