Glad another reviewer pointed out the flaws of this DVD as it saves me the time! However the Dutch edition is amazingly cheap (I paid three Euro's for my copy) so as a cheap widescreen alternative to the full frame UK edition it's not bad - as long as you are aware of the flaws. The biggest offender - thought it doesn't happen often as tracking shots and camera sweeps are somewhat lacking in El CId - is the afore mentioned 'jerkiness' of the image. It's annoying although seems to become less over time. I didn't have any problems with lip sync, however the image is very soft and the colours muted. I wanted it to look sharp, vibrant and crisp and fel the Spanish sun soaking into me!
The film is amazing, however. I'd forgotten just how EPIC this movie is - in every sense! A huge, vast canvas of emotions, exciting battle sequences, fine performances and a rousing score by Miklos Rosza. You can't go wrong and I even suspect that it's a great film to show the kids as it rivals Lord of the Rings for scope and emotion and intelligent storytelling.
So, if you can find a better copy (my hunch is the Region 1 release) go for that, but if you want a cheap acceptable edition, opt for this. But scout around as the film deserves better than this fudged release.
