One of two methods- either use a dual deck DVD/VHS recorder or a capture card on a PC.
For simplicity, you should use a decent DVD-VHS deck. Assuming the tapes don't have Macrovision, most decks are one touch.
Yes, you do want the video recorded to DVD- you can trivially copy the video losslessly from the DVD to hard disk any time in the future for editing, and it is easy to make low cost copies of the DVD to more DVD blanks. Use only Sony or Verbatim blanks and never record faster than 4x.
I would recommend a deck with a good MPEG encoder chip like the Panasonic 485.
For the PC, I've used a Hauppauge PVR150 card with hardware MPEG2 encoder chip with great results.
Both the PVR150 and Panasonic 485EZ deck do the TBC for you. When either is set at/near their max quality settings (720x480 and ~6-8Mbps), you can be assured you are capping all there is on the VHS tape.
Yes, you want to use a good quality VHS deck, a topic for another thread/forum area. I use an industrial grade panasonic AG-5700 Svhs deck. Check craigslist/ebay/videogon.
Further VHS conversion discussion belongs in either the PC area (if using a PC card) or the DVD recorder area.
However, relevant to tis VP forum, I've always wanted to convert some VHS tapes to DVD *after* running them through a VP like the Edge or other powerful deinterlacing/noise reducing hardware VP.
This would require a capture card capable of accepting a 480p signal over component or HDMI vs only 480i over Svideo/composite. Ideally, you would run the composite or Svideo out from a VHS deck to a good VP, then use a digital output from the VP into a capture card with matching digital input on a PC for an all digital path from the VP output->Pc.
There is at least one HDMI/DVI capture card I've seen in the past for PC'shttp://www.blackmagic-design.com/products/intensity/
Or use a 480p component out from the VP and cap with a Hauppauge HD-PVRhttp://www.hauppauge.com/site/products/data_hdpvr.html
The HD-PVR can cap 480i also, so you could use a good VP to do bes t in class NR/TBC/etc then cap the output via component.
Another option would be to find a quality VP with Firewire outputs, if one exists. Or use an external hardware HDMI to Firewire video convertor box, then output the Firewire to a PC or DVD recorder deck.http://www.google.com/products?q=hdm...e+convert&aq=f
Newer video editing tools on computers (OSX/Linux/Windows) may be able to apply sophisticated NR/motion adaptive deinterlacing nowadays, but I haven't checked what the best in class video tools can do recently. The idea would be to cap the raw 480i signal as well as possible, then do post processing to apply powerful NR and deinterlacing later.
