I have the following problem.
The listings for some of the channels are not correct, so I would like to use a different grabber for a few channels.

I have set up a few video sources each with it's grabber, then I specify video source I want for each channel in the channel editor. I noticed that the input connections will attach to one video source.

1. Why is the input connection limited to one video source? Since there is a video sources column per channel, why limit the whole input?
2. Will I have to manually grab the listings, concatenate and use mythfilldatabase --file ?
3. My channel numbers do not correspond to the xmltv listings (cable provider use different frequinecies). Does mythfilldatabase use the xmltvid to match the channel ?
