I don't have the crash log, the picture freezes with the icon VIX revolving in the top left hand corner.
Where is the crash log if it it generated ?
This is all down to your IPTV stream. You are likely watching the channel, and then pressing record. Which which is then effectively trying to use 2 streams. So you need a multi-stream supplier. You need to zap to a satellite stream, and set the recording via timers...
this doesnt happen to me when i do the same with a SOLO2 that doesnt have multiroom but it may be the cause in your case as your box isnt as powerful. try watching a freesat channel and then recording the IPTV SD channel.
