I'm using Rob's TV Guide and it's brilliant - no need for any flaky scripting to update on the desktop side.
It looks fine in VGA and it downloads UK XMLTV listings from bleb.org directly through your WiFi. You can have 7 days worth and whatever channels you like by modifying the XMLTV download string. It does XMLTV files too so you can manually copy over or set up a synced folder so your desktop does the downloading - whatever you like.
Give it a try, it's the most painless guide I've tried yet.
As for RadioTimes' own Pocket PC guide, I tried it and it was poor, which is a shame because their website is so good. It doesn't do VGA, so it looked horrendous and was painfully slow on my X50v. It's also a pay thing I think, so it's definately a no-go for me.
Rob's guide is now my TV guide of choice thanks to his program combined with bleb.org's brilliant free listings.
