Hi

But why is it nessesery to transfer data via the disk? could'nt it be done
in memory.
More than one person has said that it should'nt use the disk at all, so
maybe there is an "issue" on my setup.

Best regards
Anders

Yeah defragment the drive! It really helps when your video stream is
contiguous on the disk.

For a small number of streams however it does not matter much, but for a
larger number of streams (>5) it certainly will make a difference.

I must warn you there are more knobs to tweak on your system for getting
the best streaming performance, but this is outside the VLS/VLC scope.
