So ive just got a TM-NANO-SE M2 PLUS TRIPLE, i am running two lines one cable one sat, the problem i was first having is it wouldn't instalise my hard drive kept saying timeout error, ive had to use a smaller one, but the next issue is when i record and change to another channel the other channel freezes every couple of seconds and it seems the recordings don't work? Is there a setting i have wrong?
