I'd certainly love to treat VDR specially. v0.03 (not yet released) has MythTV and Freevo recording support:

Adding VDR support to the list is just as important: do you know the format (a patch or description would be very welcome), or know of somewhere documenting it?

Failing that, an ls of an appropriate directory and the contents of any meta-data containing files would be good.
