[Live-devel] key frames (I-frames) in the recorded AVI file

[Ron McOuat]

The bulk of the index could be written to a temp file as the video 
portion of the file is filled and then attached to the end of the AVI / 
QT file along with any of the other index information that may be 
required to wrap the raw index. I know, more to manage and potential 
problems with partial completion but I think the memory problem is 
solved by this strategy.
