Cablebox channels > philips dvdr 3577H GUIDE+ programlist?

Hi everyone

i got a question about this dvd / hd recorder.
i got a digibox (cablebox) of telenet (belgium).
but i don’t receive the programlist of the cablebox in my philips GUIDE+ application. I only receive the normal cable programs in my philips GUIDE+ application. The cablebox is connected to my philips en my TV with scart connection. If i want to record programs of my cablebox, i must select the channels first on that cablebox and then record with the philips recorder on channel EXT1.

Is there a way to see all my cablebox-channels in the philips DVDR3577H GUIDE+ list?
