|I have done a couple of hundred videos to DVD, and it does save vast amounts of space.|
The problem with a DVD recorder is that it may not overcome the Macrovision copy protection, and if it is within one unit with the Video, then there is no possibility of using a "Video Conditioner" box.
A video capture system in your PC will have no problem with Macrovision.
You can use either a video capture card (I have a Winfast) or most TV cards have a video in port.
The card should come with capture software, though it will work best with XP because of the file sizes needed.
You will also need a DVD burner. Dual layer discs are ludicrously expensive, but the burners capable of handling them are no dearer now, and will still burn standard discs.
Do not write to CD's - you cannot get good enough quality in the space, and my last lot of DVD blanks were cheaper than CD's!
The burner should come with DVD creator software such as MyDVD which will convert the Mpeg files you have captured into DVD format and create menus, though if you only want to watch them on the PC you can just save them as they are.
I also find I get better results if I re-encode the files with TMPGenc before writing, though this may not be necessary with other systems.
Finally, spend some time browsing on Videohelp.com.
