Something that supports
DVD-RAM is a good option I reckon. I only got the least expensive DVD recorder/player I could find at the time to see how we got on with it. I think the next one along may be something a bit more 'up-market' and comprehensive.
We too have a number of films on tape, so still need a VHS machine in the house somewhere. The worst part about swapping to DVD only is the number of films collected on tape. There are ways and means around everything I suppose but copying is such a grey area that I prefer steer clear of it. I'd rather buy the film again in DVD format. It's better quality anyway. Perhaps there's a case for the companies that sold the tape, swapping the VHS film to the DVD format at a discounted price. The copyright part of the purchase has already been paid for once. A while ago, we did see an offer that reduced the price of the DVD film by £5-00 on production of the tape (might have been Aladdin I think). The offer didn't last though and I haven't seen anything like that since.
I suppose that a discounted price scheme would perhaps be open to abuse. Lots of people might go around car boot sales etc buying up VHS films for a couple of Pounds each and then taking them to shops for a discounted price on the DVD versions.
