I have the exact same problem... What I thought of was to stream the 
whole DVB input (programs 545 and 546) to a multicast group, and then to 
create two "broadcasts" in VLM with this multicast group as input. Then, 
I would select the programs in each broadcast option. I did not manage 
to do this so far, it seems that VLM does not manage to receive the data 
on the group that is sent by the same machine it runs on...
Any idea would be great :)
