I didn't stop to notice whether it was in HD after I saw it was in widescreen.
As for the show, the BBC one is better (as usual). I really like GR doing the narrating, and the show is more about the food than the affair. The FOX version is all about the affair and very little about the food.
I also felt it was an extreme cop-out for the show to gift the restaurant all new equipment That's unrealistic. They should have made that guido sell his S-class Merc for $24K to put into the kitchen.
All in all...gotta love GR. He's harsh and critical but has a warm heart and knows he can help. In this time of political correctness, it's so refreshing to see how useful tough love can be.
