Hi Guys

I have set up on my Zgemma box to record when watching IPTV. The fault that I am having is is I go to BBC or ITV I can record ok, but if i go to a sports channel i.e Bein Sports i can record for a few seconds and then the picture freezes. What is puzzling me is that I can record BBC and ITV through IPTV.
Would appreciate if anybody can throw any ideas why this is so.
