I believe you mean "room-mate" - or are you actually living in prison? ;-)

Any cReceiver attached to a cDevice is expected to accept the data
provided in the Receive() call *IMMEDIATELY* and with as little delay
as possible. If one cReceiver takes too long here it will slow down
the whole process and eventually cause the data stream to break for
others, too. There is no way VDR can buffer this, it's up to the individual
cReceiver to buffer the data if it can't handle it immediately.
