I have had an Xbox One since launch, Day One edition, with my Sky HD box passed through the Xbox One's HDMI IN port. Since I time I cannot recall specifically, probably around a year, I have been experiencing problems with using the record and instant rewind features of the Sky HD box.
When playing back a program that has been instant rewound, the audio and video corrupt every 2 minutes or so. Recordings were mostly showing "Temp Rec" with an error of "Technical Fault - 7 (33)". While playing back these recordings, at the time the video was about to corrupt a massive box appears staying "Recording interrupted by loss of signal"
I'd tried new Sky HD boxes, from Sky and self purchased, new HDMI cables between both Sky<>Xbox and Xbox<>AVR to no avail. I'd noticed that while I was on holiday recently, all the recordings went fine, but went to pot again upon our arrival home. So, Sky HD direct to AVR, no problem since!
Has anyone else had this problem? Trying another Xbox One seems to be the only potential solution I can think of!
