We have discussed this to death already several times. ;-)

The problem is that on a busy system (multiple recordings, playbacks)
all the necessary information for the recordings menu is pushed out of
memory. Rereading this information from disk takes a long time because
the disks are already busy and a lot of seeks are necessary.

IMHO, this could only be fixed if the large data streams are limited in
the use of memory buffers. As the information is only read/write once it
is pretty useless to keep this info in memory and pushing out other
valuable data from the buffers.
