Why not simply get a dvd recorder with a hard drive, such as Sony's RDR-HX900. It has a 160GB hard drive, record what you want, delete what you want, and only record to disc the stuff you want. Great machines!
DVD recorders
Does anyone know if you can record over a tv program or other video file on a DVD disc using a DVD recorder similar to what a VCR can do with a tape? In other words, you record a program with your DVD recorder, you watch the program, then you don't need it any longer so you want to re-record over the same part of that DVD disc. Anyone an expert on this out there?
