Please don't get a DVD camcorder. We feel sorry for you making that mistake.
To answer your question, the best thing you can do is search online for the "decoder" your computer is missing. Most likely it is a 'MPEG2 decoder'.
I am new oto any kind of cam corder. Recently I have bought SONY DCR-DVD 108. I could do the lill bit of recording on DVD +RW. After finalizing I tried playing the DVD in my laptop. It does not work. It come up with an error message saying "decoder is not available". Not sure what is missing in my laptop.
