In my case, both the TV and DVD players allow for adjustment of the aspect ratio.
What is strange is that after putting in the HDMI cable, when I try to change the aspect via the TV remote, it says "not available"
Maybe it is the TV is going on the blink, because today I noticed the same problem when I try to change aspect when not watching DVDs, but on cable. thought I could change it before, seems not now.
Weird.
