Perhaps i should clarify how i set up the way i use my computer to play/record/video/dvd through the composite port. I a have scart connector with the composite connection on the other side. The scart is connected to the digital freeview box that gives me TV and with the inbuilt TV card i am able to record to the hard drive. If I want to play and record a DVD/video i put the scart in to the back of the vcr/dvd player, put the TV on channel 10 and that plays/records to the hard disc. I would then use Pinnicle to edit and put it on a disc. As far as my research goes the new Sony Vaio doesn't have this composite port, i would only be able to record tv so i need an alternative.I have used this system for about 4 years and have put all my old videos on dvd and copied some of my favorite TV programs and films to keep.
