Apparently there is a new crop of Bt848 cards giving us hazzles due to the tuner component --- The tuner component is apparently a great target for PC manufacturers to "enhance" the bt848 cards and it appears the PC tuner components are proliferating like jack rabbits :( Cheers, Amancio rhh@ct.picker.com said: > Sorry I'm a few days late chiming in on this thread -- been on > vacation down South. > I had similar trouble getting one of the newer Hauppauge NTSC Win/TV > cards working on my brother's box over the weekend.
