Question

By mistake I bought a dvd rw disc instead of dvd-rw disc and recorded a holiday video on my camcorder with it. I usually then upload the contents of the dvd onto my hard drive (Pioneer) and then download it again onto its own disc so I can delete the original content from the dvd and use it again. This works perfectly well with the dvd-rw but with the dvd rw, although I can watch this on the television, I cannot copy it onto the hard drive. I tried uploading it onto my computer (which I managed to do) but it still will not download onto another disc.
