edit - ok, this thread is now for all subchannel mapping issue. This includes two known issues: 1) the subchannel is not mapping at all. In this instance, your station's analog channel (the one we've known for the last million years) is on channel X, and their digital station is sent on on channel Y. Most of the time the station then remaps the digital channel to channel X-1. In some cases now, the Tivo is not remapping that channel. example: Channel 45 sends out it's digital signal on channel 26-1. If you tune to channel 26-1 ON ANY OTHER TUNER, it will remap to channel 45-1. However on your Tivo, it will not remap and your Tivo never sees any 45-1, only 26-1. 2) some or all of your subchannels on a station are being shifted upwards. example: where you used to be finding channel 46-1, 46-2, and 46-3 ON ANY OTHER TUNER, now there is nothing on 46-1, and everything is on 46-2, 46-3, 46-4. first post which problem you are having, then under each number, post the channels. Also, PLEASE ONLY POST THE PROBLEMS HERE IF IT IS ONLY THE TIVO HAVING PROBLEMS AND NOT OTHER HD STBs. If you have never had another STB post here and ask. If your problem is exactly like what is being stated here most likely this problem is affecting you. If it is different, feel free to post but you should DEFINITELY confirm that it is specifically related to your Tivo, and not to the station itself. MOST IMPORTNAT OF ALL!!!!! Make sure you call DirecTV on this and make sure when you talk to a tech (not a CSR) you tell them exactly which stations (including call letters) you are having problems with. It will probably be easier for them to fix if they could understand why the unit is doing this on some stations and not others. 1 - WMVS Milwaukee, WI Tivo will not scan channel 8-2, nor will it remap it to 10-2 when manually tuned to. It WILL see and map to 10-1 and 10-3 through 10-6. Only 10-2 is missed. 2 - WDJT Milwaukee, WI on channel 46 all subchannels (3) are shifted up one channel. 46-1 is blank and 46-2 though 46-4 carry programming. This causes the DirecTV guide data on the channels directv has 46 mapped to to be incorrect (58-1 through 58-3).
