i purchased a hauppage wintv pvr 350 model 990 card and installed R4V5. After reading on some posts about new tuners i have followed the instructions for installing new ivtv drivers and firmware at the thread http://mysettopbox.tv/phpBB2/viewtopic.php?t=2995

after i reboot, i get the error message that no screens were found.
it also states that ivtvdev: no matching device for instance ( BusID PCI:1:8:0)

i am wondering if anyone has a fix for this

Your 350 card is probably not at that address. Do is lspci and look for the proper address. It's probably the last (or close to it) think in the list. There are a bunch of posts with more info on this.
