If I have a set of recordings that go over more than one page (i.e. more than 7) in the Recordings -> Most Recent section and then play and delete a lot of them to leave, say, 3, then the Recordings listing will often repeat the recording list multiple times!
For example, if I have Prog1, Prog2 and Prog3 left after the deletions, then I'll see:
Prog1
Prog2
Prog3
Prog1
Prog2
Prog3
If I delete, say, Prog3, then I'll see:
Prog1
Prog2
Prog1
Prog2
Prog1
Prog2
If I put my HDR1000S into standby and then back into normal operation again, going back into the Recordings section shows just Prog1 and Prog2 without the repeated listing. Since there's an easy workaround, I'm not too bothered, but I think this bug has been in pretty well every firmware release I can remember.
