From VDR/INSTALL:

If your video directory will be on a VFAT partition, add the compile time switch

VFAT=1

to the 'make' command. Alternatively, you can call VDR with the command line option '--vfat'.

Of course I forgot this. Sorry about that.

The ':' was replaced with '.' in version 1.3.32. The reason why it has been used originally was that I wrote VDR on an actual operating system and didn't think of that M$ crap ;-)

I was using 1.3.31.

If I compile 1.3.31 again with VFAT=1 option, does it still support old format filenames with ":", or do I need to rename every video-directories to a new convention?

Probably upgrade to .32 would rename everything?
