Just a little warning in case this happens to anyone else. I record to HDD, use chapter markers to chop off the dross at the start and end, then high-speed-dub to DVD-RW. The discs I send off to a friend in the USA (I'm in UK), she watches them and sends them back, I reformat and reuse them. I've had two discs recently where everything appeared perfectly OK, until I tried to actually watch the disc, when it failed with a "disc needs cleaning or is damaged". The same thing happened when I tried to copy the disk back to HDD. Of course I had already deleted the recordings off the HDD since the dub to DVD-RW went perfectly. More fool me. Now I think I'm going to have to dub back every disc to make sure it's OK before I delete the recording from the HDD, which will double the time taken to make each disc.
