Here's mine. It seems that you will almost always get a zero byte 
recording if you use a card to record different channels one after the 
other.

As seen in the log below, the services reported the first time isn't 
correct for the current channel I want to record, the services was from 
the previous channel.

So far calling TuneTransport (IIRC) a second time always work. I don't 
have any zero byte recording once I did that.
