Terrible image on TV

[sniperpenguin]

OK, Im new to hooking PC's up to TV's, so be gentle

I have a shuttle SN45Gv2 running a basic Sapphire 9200SE and XP Pro going into a Samsung 32" TV (Flatscreen, but still CRT) via S-Video to composite (decent cable). The image is blurry as hell.

Not sure what the problem is

1. Rubbish card?
2. Not running Windows MCE? (Yes, I know its basicaly XP Pro with a pretty interface + codecs)
3. Drivers? (was only running XP's radeon drivers at the time) - I was halfway through installing the catalyst drivers when the shuttle went loopy and started rebooting randomly!
4. Plain old resolution?

I'm humble enough to admit I've no idea with media machines

Well Im using the latest Cat's of the ATi site. i'll:

1. Whack it down to 800x600
2. rip out and re-install the cats (getting the video.ini error at the moment when I try to install)

Just wondering... if TV's always have a terrible display, why does MCE appear to look OK on a non-HDTV?
