Re: Allocation of a stream descriptor for MPEG-2

[Gorry Fairhurst <gorry@erg.abdn.ac.uk>]

Thanks Mike, 

This looks like the correct thing, which registry item should we be asking
to create?

If we have support for the same type in a DVB multiplex, do you know if
there is any merit in co-ordinating this process?

Best wishes,

Gorry
