Hi,
Timeshifting is working fine on IPTV that are limited to 1 stream.
It is recording that is the problem due to the 2 stream approach in E2.
The workaround would be able to define an automatic zap to a real DVB service when a recording is started on an IPTV stream.
The more complex approach is to be able to define the url where 1 stream only is allowed and then to immediately greyed out the channel from this "URL" and then leave only free and zap to non limtied DVB or IPTV stream.
