If all three sources had the same channels on them....

Analog cable < digital cable
SAT contains some of the cable channels + a lot others.

web site is good in info, but does not cover all channels available on 
digital cable. Digital cable has had several failures on EIT, seems to 
be improving though, and generally is doing a pretty good job. SAT EIT 
is going pretty good, except for the English channels, where i still 
have only EIT-now/next. (I have Astra 1 and Astra 2)

At the moment i have the digital on EIT only. I can change to mixed, but 
that results in several runs on the web-scraper, which is not friendly 
to that website. It is possible though... Still, the channum's on those 
are most certainly not the same!

My protest is the assumption that on all occurances of the same channel, 
the channum will be the same. Having them different results for me in 
the following nice behaviours:
- easy to select whether to watch from analog of digital (cable or sat)
- easy to program preference on what source to record from
- easy to see whether EPG data is available on all
- i can see them separate in mythweb. So far, for equal channum mythweb 
will show only 1 entry. If they are truly the same, that is correct. I 
like to be able to easily check from which source a program will be 
recorded though....
