A QAM64 scan detected 150 or so entries on 18 frequencies and a QAM256 scan detected about 15 entries on 5 frequencies. Is it expected to see both modulations used on the same cable? One thing I'm a bit puzzled by is that nearly all entries have 0 for the video pid. For example, most frequencies have a handful of entries with different audio pids but the same video pid of 0. Is that normal? I didn't want to impose on my neighbor any more than I already was, so I didn't do an exhaustive check of every detected entry. I tried around 35 or so and was never able to find a signal with azap. Unless anyone has other suggestions to try, I guess everything on my cable system is encrypted. I'm dissapointed, but not terribly surprised by that. I'll just go to my backup plan which is to hold onto the card and use its ATSC capabilities when I get an HDTV. Finally, my Fusion card still has a very poor picture using NTSC capture (very high brightness and washed out colors) so any help with that would also be appreciated.
