I've put recordings from our video recorder into a file for sending to friends. It's worth bearing in mind though that these files tend to be pretty big. I stored and sent them in the
.wmv format.
I bought an inexpensive video capture card for the purpose. The lead that comes with the camera plugs into the card and the software supplied in the package captures the video recording for saving as a file. The file can subsequently be burnt onto a CD-R or DVD using appropriate software (the choice is wide), this is providing you have a DVD burner of course

.
If the camera is a fairly new one (mine isn't) a firewire connection can be used instead. Just buy a firewire card instead of a video capture one.
If you want to copy entire video E-180 video tapes, it might be worth considering getting the sort of DVD video recorder that fits under the TV. These are becoming inexpensive now. The cheapest I've seen in UK is £120-00. Unless you already have the computer video capture card and software, this option might be worth considering expense-wise. You can then record and play TV programs on it too. A DVD video recorder doesn't need any software or interface. The AV lead goes straight from the camera (or VHS video recorder) into the DVD recorder.
Your own VHS video recordings will copy to a DVD. Be aware though that purchased VHS movies may not copy to a DVD in the recorder. Something called 'Macrovision' may well kick in to prevent copyright infringement.
