Since you wrote in your other posting that you have the same problems
with actual recordings, this "buffer reserve" in Transfer Mode won't make
any difference.

I assume that there is a problem with this C5 stream, maybe something like the
problem we recently had with the German RTL stream. All of a sudden recordings
from that channel could not be replayed any more. It turned out that the firmware
dated 2002-04-15 was still able to replay these streams, so maybe you should give
that a try.
