Sounds very good. A lot better than an arbitrary Id-String. At least these 4 
or five Id are unique and the data for tuning is provided over dvb, so 
changes will be catched and channels don't disappear (like Disney/Planet). 

Futher I searched a lot on lyngsat about these obvious "french radiostations"

As I catched it was 12207:v: (tp90 according to lyngsat) the Sid in the former 
mail was wrong. 

The only channel I found there till now is:

Name			|  SID	 |  Apid
-----------------------------------------
 Hits Music 		| 8503 | 1975 
 Classic 			| 8503 | 1977 
 Jazz    			| 8503 | 1979 
 Chanson Française	| 8503 | 1980 
 Vinyl Culte		| 8503 | 1981 
 Planet Sound 		| 8503 | 1982 
 House of DJ's		| 8503 | 1984 
 Rock'n'Pop		| 8503 | 1985 

And in these theory they should have RID's ...
I could do more search on lyngsat (think lyngsat is actual and proven, or am I 
wrong ?) if it is helpful. Right now I dont know how to see these PMT/PAT 
data, but will try to figure that out. 

For people , who want more than one channel-entry for one channel with 
different language, there will be the coming "favourite channels" there could 
be according to the provided data the language be defined ( first language, 
second, third and so on) 

Is there any reference to read about the informations provided by the 
Transportstream ? 

Thanks & Greets

Steffen
