Burning DVDs on my SonyVaio PCG215M laptop

I would like some advice on which DVDs/CDR or CDRW to buy, so I can burn some home movies. I bought a sony pack of CDRW in france but right at the end of trying to save a project an error message occured. I have only recently started saving my video clips from camera to windows movie maker, but need desperately to get them off my computer now as its running slow. if anyone has been abel to do this effectively can they let me know. Im presuming that it is possible, unless someone knows otherwise.

 

use sonys own dvdrw.sony dvd and cd burners are very tempermental.I know I have 2 on pc ang 1 on laptop.you can put a disc in thats brand new and it says disc not empty

 

Not had one coaster with Verbatim DVD-R's.They are excellent.
