Had my XS34 for about 6 weeks now. Very pleased with it. Great flexibility and recording quality. However, once or twice, having set up the timer to record from SKY (AV2), I find it has recorded the programme with sound but no picture. I must have recorded a hundred programmes with no problem. I always use the satellite control facility, and find it to be very reliable. After it has recorded with a blank screen, it stays with a blank screen. NB I never turn off my XS34, the timer is activated from the 'on' state. Any thoughts?
