Select a show from the My Shows list, watch it to very near the end (all but the ads, etc), give it a <- to get the save or delete - and it jumps to the next higher show in the My Shows list. If you're not careful, you'll delete the next higher show from My Shows. It doesn't happen every time, but mostly it seems to. If its already the top show in the list, no problem, and it never jumps to a lower show.
