There's a "Mark" button on the Rio remotes, which will be supported in v1.1 (IIRC, 7 does the same on the Kenwood). We intended it to be used for marking badly ripped tracks.
You can search for these when you get home and run up emplode. Then you can either replace them, or use them to create a new playlist.
For generating lists of stuff you like, there's no way to do this properly on the fly - the disk is read-only, so the player has nowhere to save it, should you yank the power.
Just curious on this... How are you marking the tracks if the disk is mounted RO? Separate RW partition, or NVRAM?
