>What are the pitfalls?
You need to find out if your older DVD player plays both plus and minus formats, and if not, which one it supports.
If it only support plus (or minus) then you need to make sure you only use the same format disks on your NEW DVD recorder, so you can play the DVDs in your old DVD player.
I have always recorded my DVDs on minus disks, and never had a problem (not saying it is the best, but it works for me).
Finally, have to agree with ACtheTROLL, buy a DVD recorder (or other device) with a hard disk in it and record to that and ditch video tapes.
I have a Sky+ box with a hard disk in it and it is a breeze to use. No rewinding tapes, no wrecked tapes, press one button to record and it knows when to start and stop recording.
Also note VHS tapes are not digital, whereas hard disks and DVDs are digital.
With VHS you go from digital TV, to analogue tape, then back to digital for the final DVD so wil lose quality.
If you record to hard disk you are going from digital TV, to digital hard disk, to digital DVDs. Much better solution.
