dunno what ultramon is, but i got no problems with my AIW9800se, dragging between monitor and tv, with just the standard drivers.
also, any generic tv-tuner program will work just fine with the ati tuner - i even did one myself using directx8 sdk

but i love the mmc programs and even wish i could use them for my pinnacle tuners on other pcs... so i dont see what you're complaining about.
