The change to GETOSPACE is wrong, it basically reduces the returned
number of fragments by 1, possibly returning a negative value. The
returned number of bytes is also truncated.

The change to GETISPACE on the other hand looks correct, but I have
no idea how fixing the record operation would have helped playback.
