Channel 17 ran an informative crawl during last night’s Olympic broadcast. It regarded cable customers who get to their HD on NBC by literally tuning the TV to 17.1. If these viewers cannot get their TV to tune into the HD version of the Olympics, they should try rescanning their channels. Incidentally, this also applies for those periodically having trouble tuning their TV ( not their cable box) to 5.1, 11.1, 50.1, etc.

When the TV runs its new channel scan, it will find the hidden channel to which Time Warner has newly assigned WNCN’s HD channel. (Periodically Time Warner will reassign the actual location in the bandwidth where some channels exist in order to get more efficient transmission. The cable boxes and CableCARDs do a fine job of detecting these new addresses, but QAM tuners, which people use when they tune in to 17.1, need to be manually remapped).
