I am looking at picking up a small 4x3 set for my bedroom. Does the 16x9 mode only work with anamorphic DVDs? Can it work with an HDTV signal as well? I am assuming you will need to set the DVD player as being set up on a 16x9 set. As I don't have and HD signal yet, I do not know if the HD receiver gives you the same choice, and therefore you may be able to do the same as with DVDs. Thanks.
