Hi, sorry to bump, but I thought I would clarify how this works as some people are confused.
Friends was filmed on Super 35, which has an aspect ratio of 15:9. Because widescreen television sets have an aspect ratio of 16:9, this means that unfortunately a little bit of cropping on the top and bottom of the screen is needed to fill the 16:9 frame. If you go back to the DVD/HD comparison shots on the first page of this thread, you will see what I mean. It is cropped, but only a little bit, and nothing major - not at all like a 4:3 crop to 16:9.
I have no idea how the graphics are done though - because they look exactly like the 90s graphics - it doesn't look at all like 2011 CGI graphics. Look at the Friends logo on season 2 - it doesn't look like a crystal clear SVG logo, which strangely is better. And they are all faithfully re-done. Even odd things like the names not being aligned properly on the pilot is done - however they've used the wrong font on most of the season 1 episodes, by using the font used in the titles after season 6 (when Courteney Cox became Courteney Cox Arquette and a smaller font was needed) which is a little disappointing, considering they've recreated everything else perfectly, such as the other odd thing on season 2 where the Friends logo on the NY skyline flashes off a millisecond before the scene changes to the fountain.
Hope that clears things up.
