Do these work in the same way as camcorders with a hard drive? Eg, Do they record seperate clips that you can watch one at a time on the camcorder, or delete scenes? And you don't have to find the end of the recording to start recording again?
They work similar to hdd camcorders, and depending on the type of disc you can delete clips and re-record.
I had a Samsung DVD camcorder, wasn't the cheapest but wasn't too expensive and recoding to disc is slow and clunky. I wouldn't recommend DVD camcorders.
