I am using a Mediastar HDX 9100. A couple of days ago I lost audio on 7mate and Gem.

Checking reveals that there is no APID for those channels. Easy enough I thought just go in and manually input them. Not so easy - there does not appear to be anywhere that I can do that.

Try the digital TV, rescan because of all the channel changes - audio on those channels.

Pull out the old DGTEC SG-HD5370, rescan because of all the channel changes, and there is audio on these channels. Hmm.

Connect the second 9100, rescan and damn - no audio!

Any ideas.
