I tried playing a foreign dvd in my Toshiba SD2700 dvd player and now whenever I play a regular dvd there is this big black square on top of the movie that occuipes 95% of the screen. It's weird because the menus play fine and when you pause the movie the square goes away.

Someone told me it was because the player got switched into a foreign format by that dvd and I should unplug it for a while to 'drain' the memory and switch it back to the regular format. Tried it and it didn't work..

Any suggestions??

Thanks!
