I think you're right, this is one of the encrypted channels and the STB must be decrypting it. The Firewire method is the only way to digitally transfer these files into a PC without a CableCARD. > If the channel however isn't encrypted, there are other options > (recording directly in TSReader using an ATSC tuner card that can do > QAM).

Too bad, by QAM-capable ATSC card (Fusion HDTV 5 RT Lite) just died recently. I'm still debugging it. I could've used like you said. However, I wouldn't even know what frequency to look for this channel because I don't have the frequency-to-channel mappings that the STB gets. I just saw TSR is capable of reading the PSIP mapping data in the streams but TSR doesn't support my (broken) card anyway. > I've seen TSR compatable QAM cards on ebay fairly cheap these days. > Specifically, the newer version of the Technisat Airstar HD5000 (but you > have to make sure it's the newer version - the old one doesn't do QAM). Thanks for the tip. I'm considering getting a new QAM card. However, it can only receive a bunch of channels as most of the channels are encrypted on my cable. It was nice to capture the unencrypted on-demand streams, though. :) That's the best way to pay for an HD moive and get it into your PC. No ripping, no buying HD-capable optical drive.
