ok, please avoid any sony bravia s series if possible coz that's what i'm using. well, if u have close friends or relatives with lcd panel, try it on first.. if not possible, go for any lcd tv with full hd OUTPUT display resolution. which is capable of displaying at 1920x1080 pixel. that's all i can help with ur budget. about that 100hz thingy, i don't have experience about their price. but i do know they can make ur movie looked like it was recorded from ur own handycam (which is a unique feeling i might add).. coz it will play at higher than 24p framerate.

A cheap Philips Home Theatre at RM999 that comes with DVD Player with upscaling capabilities and a usb port for images n videos.. however, it only have a digital in.. no optical..

No.. Digital In has a connector exactly the same as RCA connector.. aka RGB cables.. or Component cables..
