I’m fairly new to ConvertX to DVD so I was just wondering… is it possible to split a movie onto two discs?

I just bought some TDK DVD-R discs (which I’m not entirely sure will work on my DVD player anyway…) but the thing I’m trying to burn keeps saying the disc isn’t large enough… I don’t get a lot of time to go out and buy DVD discs, so I was just wondering if it was possible, and if it is… HOW do you do it??

Please help!!
