Okay, I added all those flags, but there was no change.

After adding them and retesting, I thought it might be a good idea to do a serial-log - so I disconnected the empeg from the network, connected it to a PCs serial-port and played the same two tracks about ten times, but there just wouldn't be a pause...
So I thought, maybe this just happens when the network is connected...!? At least I cannot recall having these pauses in the car...
I attached the network cable while the player was playing, and in the next few minutes, I had four lines popping through the cable:

Vcb: 1362393
Vcb: 1
Vcb: 1362393
Vcb: 1

I saw no such lines before I connected the network-cable - is this of any value ??
But still: I didn't get the pauses again, so I restarted the empeg completely, to be sure it's logged in to the network (dhcp...) correctly.
Still no pauses (but I didn't try THAT often)...
I started emplode - and on the next track-change, there was the pause again.
No further Vcb-lines, though...

Does the empeg 'know' when emplode is on ?
