My Humax PVR 9200T works fine in every way as far as I can see, except one. If I edit a pre-recorded programme it creates problems on the soundtrack. For example, if I recored a prog to hard disk and then decided to delete the commercial breaks using the editing facility provided by OPT+ it is easy enough to remove the 4 minute segments of adverts. However, when I listen to the edited programme without the commercial breaks the sound level oscillates for a about 10 seconds during the bit of the programme that immediately follows each deleted segment. This change appears to be a permanent feature of the edited file. Anyone else noticed this? I can't believe that I've got the only machine that does it. Anyone found a way round it? Thanks for any help.
