Hi there, I have a Sony Vaio desktop VGC-LS1, with a built in NTSC TV Tuner card. I want to install an ALL systems i.e NTSC, PAL, SECAM card like this one........ http://www.tigerdirect.com/applications/searchtools/item-details.asp?EdpNo=3148961&csid=_21. I have 2 queries: 1. The card says that the machine should have a VGA card, but my desktop has a Intel mobile graphics acelerator 128 MB.......would it work with the Vaio machine? 2. Should I need to disable the built in TV Tuner card when I use this one? Hopingto hear your views, Regards!
