All of the above still sound like kludges. Creating previews when the browser is 
just about to display a whole list of them is probably not the best of designs.

When your list of previously recorded is in the hundreds this can take a whole 
lot of time - and it doesn't help that 'Previously Recorded' /always/ defaults 
to the 'all recordings' selection.

The appropriate time to generate these is when the recording is completed.
