Hardware capture-encode device/PVR?

Anyone have experiences to share on a hardware capture-encode/PVR?

Some are external boxes:

Plextor PX-TV402U ConvertX & TV Tuner

Some are PCI:

ATI TV Wonder Elite

Anyone have a recommendation for me?

Big difference seems to be whether hardware mpeg-4 and div-x is available on a device and/or whether that is needed.

I want to convert a boatload of VHS tapes to DVD, but I'd also prefer a device that provided PVR and TV Tuner capabilities.

Cheers,
