ghosting is common to analog signals but not to digital
Ghosting can happen
on analog signals, I'd hardly call it common, if you're seeing ghosting it typically means something is wrong, or something in your setup is junk.
What is common is ghosting when using a low resolution connection on a high resolution display. The reason for this is that it creates a perfect storm for ghosting due to noise in the power line.
If you don't have one pick yourself up a decent power conditioner run your TV and your Xbox through it and marvel at the improvement in picture quality.
I never used to use them but then I started getting some ghosting when I added a switch box and ran some longer video lines (it's a projector setup). I decided to get a power conditioner I spent $40US and it made a huge difference in picture quality... hands down the best $40 I've spent on my HT room.
