Hmm, how does it work on a transponder with a fixed bandwidth ?

I assume that a generic satellite transponder has a fixed bandwidth
of approx 45Mbps ? Since the transponder usually (not always) has
mutiple TV-channels and audio channels, they can not all peak
at 8-9 Mbps at the same time. Is there some reserved common
pool of spare bandwidth that they can share and use if available.

If yes, then I assume they sometimes can not use the extra bandwidth
leading to a temporary corruption in a stream ?

Kind regards
