I assume you're referring to the "overflow buffer" for the video decoder.
According to a posting from Ralph Metzler a while ago that can only be
used in live mode, not during replay. So there might be a way of getting
more OSD memory in live mode, but during replay we would still have to
do with less. I'd rather not have to differentiate between live mode
and replay when opening the OSD. Besides I'm not even sure whether that
buffer can be easily reallocated dynamically.
