I have a DVD recorder that records onto DVD-RW disks. I also have a PC with a DVD writer and DVD creation software. The DVD recorder records TV programs in Video Recorder Mode format. I can then use the PC software to convert these files onto a new disk in standard DVD format. (Audio TS, Video TS and .VOB files) The video recorder can format the original DVD-RW it recorded to, making blank and available to use again. The problem I have run into is if I save something in standard DVD format onto one of my DVD-RW disks, and then format it in the DVD recorder, the DVD recorder gives an error message if I try to record to it. It appears the DVD recorder format process does not remove everything the PC did to the DVD. What I need is some way for the PC to return the DVD to the condition it was in before it was ever used, so that I can re-use it in the DVD recorder. Does anyone know a way to do this. (There is no point buying expensive software, because the disks are only 50p each) Format is not the same as blank. Only disks formatted in the DVD recorder will work in the DVD recorder. The problem is if the disk has been formatted by the PC, formatting in the DVD recorder is not good enough.
