It is really different: several tables linked together in some weird 
ways (or perhaps I see it like that because I do not understand the 
full format). I can just decode the titles duration and start time, I 
know where the summaries are but I don't know how to tell which summary 
corresponds to whixch show, hopefully fixed soon.

Thanks a lot, I will try to hook my code into myth classes.
