Can you get WTV files to play on Vista (stream from a 7 computer) without converting? Or is it possible to get 7MC to default record in .dvr-ms? I have a copy of Vista around and an extra computer. Really don't want to spend more money than I have to for a computer we will use very little.

Yes, download and install the TV Pack for Windows Vista Media Center.

You'll need to download from a torrent site or similar site though as it was released as an OEM update only.
Note: TV Pack was a horrible, poorly tested feature pack primarily designed for the Asian tuner market. If is fine if you are only looking for playback usage but otherwise stay clear.
