Yes, I would like to see the program you wrote since I have made some
progress in getting the pvr250 working in another box on my local
network. I was thinking of just doing scripts but it seems you have
taken it a bit further.

I've also tried moving the pvr250 to different slots on the
motherboard (Soyo KT600) to no avail.  At some point I may continue
with other combinations/updated bios/settings/patches.  As Greg (grog)
mentioned, it sounds like something deeper is going on with the KT600
box.

In the meantime I put the pvr250 card to another box (Soyo KT400
motherboard) and it seems to be functioning fine with that hardware
combination/settings.  I am able to view/record as it should.

Actually, the pvr250 has a better tuner than my standalone TV ;-)

If I can get further information from the KT600 box or get it
working with the pvr250 I'll post it for the archives.  I'm willing
to move the card back to that box for testing if someone has
any suggestions or things to try.

Thanks to all for the suggestions and pointer!
