Channel tuning broken with DVB-C
Contents
Whats wrong ?
With some cable providers scanning for channels seem to work fine, but its not possible to tune the channels. Two problems are known:
1. Some provider change the modulation of satellite feeds for DVB-C but don't modify the device information. One have to scan each frequency manually but there is no way around it.
2. These providers have different regional channel lineups but generate the SI in a central place. They transmit for each region one NIT all the time. The DVB standard has a flag to indicate whether a NIT is for the actual network or for an other network. This information is not correct for all but one of the regional networks. One has to know the network id to get the correct network information table.
There is only one simple solution for these problems: Talk to your cable provider they need fix it!
How can we fix it ?
