A week ago, something changed with a few of the San Francisco South Bay Area Comcast broadcast channels. When 709 (KQED Channel 9 HD) or 710 is recorded, a TS download via kmttg and Tivo Desktop works. But when 1009 or 1054 is recorded, the same download only gets you the audio track - no video. There may be others, but I have thoroughly checked. Since I have OnePass enabled for all channels, it seems to pick anything it wants. I do not know when 717 vs 1060 or 710 vs 1054 are chosen. So I just went into channel setup and deleted all the 1xxx broadcast channels. Another thing - Comcast lowered 709 bandwidth to about 4.2Mbps about a week ago. It's now the same as 710. OTA broadcast is ~10Mbps and ~7.8Mpbs respectively. It looks like the other broadcast channels still are close to OTA bandwidth.
