on a side note .... what is the firmware of your SD-1200? I'm having problems with mine (manufactured in JANUARY 2000, you can find this date on the back of the unit) with a firmware version of 1.3 - R1 (turn on the Toshiba unit, hit ZOOM, 6, 0, 6, ZOOM) up comes a display screen showing a summary of features supported by your model DVD player, you'll see what I mean.
Don't worry, you can't change anything, thats hardware, this is just a summary of features :-) Firmware is actually the first two lines, ROM1, and ROM2
ROM1: Ver. 1.3 - R1
ROM2: Ver. 1.3
I have problems with certain movies stuttering and de-synching, in particular The Haunting, and Dark Crystal have exhibited these conditions. Also have seen American History X do it. These conditions do not always manifest themselves, just on occassion, disks are new, work fine in a Panasonic machine. SD-1200 is new too ... going to talk to Toshiba again and send it back, maybe its firmware, maybe its another flaw. *shrug*
Hopefully you're having better success. Otherwise its a wonderful unit, with great playback (crisp, clear :-)
