My DVD player has seemed to have a higher incidence of getting stuck. Could be the series I've been watching (Get Smart TV series, borrowed from Stacey), but I had one of the LotR commentaries on in the background while I was doing something else and it stopped too. So, we'll see.
Right now it's just irritating, but it seems like I'm going to have to get another player (Blue Ray?) sooner rather than later. Hurrumph. :/
