I have just replaced my STB with a new LG HD STB and am very happy with its performance.
The LG STB I have is an LG LST 5100P. I'm as happy as I can get... there is only one thing, this has made me wont to replace my fairly new TV..
I have an Omni Wide screen TV with just about every input I would have thought I would ever need..

However the only input that works correctly with my new LG STB is the the Std AVI (3 cable left, right, video) and I can only use the lowest settings for the STB or I have no OSM (On Screen Menu).

So am I missing much by having to run in 576i yprbr.
I'm happy enough with the clarity and crispness and sound..

but I think that if I could use the RGB or DVI component inputs that are on the TV I would getting a better experiance...
