another +1 "Ad Nauseam"
If you MUST have a 32 bit OS for some older apps you say you already have vmware so you can run the 32 bit OS under it.
I'm still using XP Pro for a "Minidisc" application that only runs on XP -- Sony won't supply any VISTA / W7 upgrade for it. This works just fine on XP under VMWARE.
Sometimes on Music gigs live recordings / demos I need a Minidisc recorder. Ipods just don't hack it for Live Recording of Uncompressed Music I'm afraid.
Also listening to very highly compressed MP3 music with hideous bud earphones isn't my way of enjoying music.
Minidisc might be "Dinosaur technology" but the quality can't be beaten --especially with a nice pair of BOSE Noise cancelling cans and you can still record in uncompressed WAV.
As for TV cards -- Hauppage is actively "Beta-ing" WINTV7 which works (a little) on X-64 W7. Works OK in VISTA X-64. Pinnacle also is developing stuff.
Most cards seem to work OK anyway with Windows Media Center (both w7 X-86 and X-64).
