I have the Hauppauge PVR250, which is similar to the PVR350 mentioned above, except without the FM tuner.  It doesn't compress using mpeg4, but it does an excellent job using mpeg2, and I would say it produces one of the best captures of standard definition video in real time.  At the highest quality setting, the file produced is 2GB/hour, and you can choose lower settings to save space.  It does not have a DV input port, but you could hook up a DV camcorder to take your DV video via Firewire and convert it to composite or s-video, which it does accept.  If you don't have a DV camcorder, a Canopus ADVC-100 unit will do the same conversion.

The compression ratio is higher in mpeg4 than mpeg2.  The problem is the requirement for both DV input and mpeg4 compression.  This site has products that do one or the other, but I don't see one that does both - you can see for yourself: http://www.visiblelight.com/mall/catalogview.aspx?cat=21

It looks like it does what you require and it does it in real-time...are you comfortable with the $3300 price tag?
