Panasonic Vga to Scart!

Hey Folks,

Been setting up a home theatre box for longer than I care to mention, started with mce then myth then back to mce, got everthing running just as I want it and have one task left, widescreen to my Panasonic TX36PL30 CRT TV, currently have it connected via svideo which is okay at best, but doesnt give me widescreen!!! Initially had this issue with Nvidia, but have moved to a Radeon 9550 and have got my SBB92H vga to scart cable from Keene!

Now this is where im hitting a brick wall, got the cable plugged in, PC vid card sees the TV (well default monitor) but I aint seeing anything on the TV! If i flick between AV channels on the TV i think i see the windows screen (if it is the frequency is all over the place).

I really aint sure where I go from here, power strip is installed but i aint even getting a slight picture as a starting point to be able to start tuning the resolution!

Any pointers muchly appreciated! I thought I had bought the correct cable!
