I actually just setup IPTV in addition to my current DVB-S channels.

Did you import an m3u file with the tvheadend wizard? You will need the latest TVheadend Add-on for that.

It works if you scan all muxes, just make sure you change the option for a timeout in the settings so it doesnt flood the IPTV server. I found out it only scanned about 3 channels at a time unless I added a 2 second timeout to the can in the mux settings.

I have it up and running now and its working fine, not worked out the EPG stuff yet for IPTV though.

First, thanks for your reply.
No, I didn't use tvheadend's wizard, but I configured new IPTV network and there I added the url; I'm using TVH server 4.2.
I did not understand..do I have to scan for each single mux in m3u list?
Maybe the issue is that I didn't change the option for timeout in settings.
I'm going to try again on this evening, I'll keep you updated.
Thanks again.
