I did a tcpdump on my loop back device, and saw there are spaces where
there should be newlines ('\n'). I enabled the commented out logging in
mtd and the mythvideo plugin, and see the same thing - spaces instead of
newlines.

This means tokens are not properly parsed on the receiving side, so it
never knows the DVD is really there.

The QString message.append("\n") mythvideo/mtd/mtd.cpp MTD::sendMessage
is sometimes adding a space rather than a newline.

I'm not sure if this is a mythtv bug or QT bug, I haven't figured out
any other details.

I'm using the fedora 9 qt3-3.3.8b-14.fc9.i386 and qt3-devel-3.3.8b-14.fc9.i386 

If anyone has a potential fix or suggestion let me know ...
