@fnu

Thank you Frank for your kind help. Analyzing the streams was the first
step towards success.

Finally I found the reason why RID would not work with my IPTV-Channels.
It's very simple: apparently SVDRP does not like an NID of zero. As soon
as you set it to 1 the RID can be used as well.

The import of EPG-data from epgdata.com is now working fine for my
IPTV-Channels from a1tv.

Thanky again

Kind regards
Michael
