I just bought a Panasonic blu ray writer with HDD that will allow me to store the contents of my sky hd box on the hard drive via scart input. This is done in real time, so to store 10 hours of programs, takes 10 hours. This is not a problem as I leave it running over night, but the 10 hours of TV, is stored in a single file on the HDD. I can then transfer this to my PC via USB. However, I would now like to split the single file into multiple files, say one for each program, so I can write them to dvd individually. Is there any way I can achieve this?
