OK, I'm having a hard time trying to express my self :) But I think I'm 
getting the picture, see further down...

Sounds promising for my needs. To make sure I understand I'll try to 
summarize;

If I populate a channel with custom EPG-data and setting <table id> to 
0x6F and the <event id> to some random made up unique value the EPG-data 
will always be overwritten by events coming from the providers data 
stream as long as the <table id> is less than 0x6F and start time are 
the same no matter what the <event id> are?

Richard
