I have had problems burning to DVD-R discs, and after taking advice I now use DVD+R, which seems to work very well.
I am now able to burn AVCHD format camcorder footage to blank DVD+R discs. I use the pc burning facility rather tan an external burner.
My remaining problem is that I can burn only to a blank disc. If I burn even a small file and then try to burn another file I get a message to insert a blank or re-writable disc. I have read, however, that DVD+R discs can be recorded to until the available space is used up.
I would be grateful for any help or advice. laurence1to3
