You were right; I scanned the 2 transponders you gave after 7pm and the 2 children's channels were replaced by BBC3 and BBC4.
Apologies for not spotting this sooner and thankyou for your help.

Nope, I've just scanned the channels you gave and no joy. Did a complete scan again, still no BBC3 & 4 (not in lost channels list either).

Peculiar, because other progs like DVBViewer and DVBDream have no problems detecting them.

So why don't I use them? DVBDream, for my system, records 2KB files ...

Just checked for Channel Five and the single unlocked version is there - my mistake (I'm new to ProgDVB). I'll see if I can find the channel data for BBC3 and 4.

I've just installed ProgDVB on my quad core XP PC and all seems to be working (on freesat)
However, channel Five is listed as NOT free (when I know it is) and BBC3 and BBC4 are missing from the list.
Any ideas anyone?
