I purchased a new Sky+160 about 3 weeks ago. I am having sound problems. I experience sound drop-outs and sound break-ups. However, I have another unusual sound problem. When watching a recorded item, I fast forward at x30 to bypass the adverts, the programme resumes with the soundtrack from the adverts playing over the programme instead of the expected soundtrack. This problem is not exclusive to the adverts section, it can be occur anywhere on the recording where fast forward is used. Any ideas as to the cause?
