Finally took the time to play around with these tonight. Wish I had sooner, one is dead and gets no analog signal. It is only detected as a “digital antenna” tuner, useless for analog cable TV. With the one working it spikes the CPU, so I don’t think the PC could have handled 2 tuners going at the same time. The main problem I did not see coming is these USB tuners need the CPU to do the brunt of the work, where a tuner with chip based decoding does the work and does not tax the PC. Wish I had skipped this purchase, not only is one dead, but they suck resources far more than I expected (AMD 3200+, 1gig ram, Vista premium, SATA).
