I don't think it's a network setup. I think you'll find some answers in
the discussions about the length of time it takes some setups to change
channels. There's quite a pipeline that data has to go through before
it's written to the disc, and available for reading by another process.
I'd suggest pausing playback so that you're at least 15 seconds behind
