The last two weeks, ESPNs 206 and 209 and Versus have been in a 4x3 format. All other HD channels are 16x9. The ESPNs at 72 and 73 are 16x9. This is on both of my systems. The funny thing is I haven't seen anyone else comment on this. What could be wrong??

Last I checked they were 16:9 on the MPEG4 channels for me. Only thing I can think of is your watching the SD versions by mistake, I can't think of any setting that would just impact 3 channels.

I am watching the HD channels. When I go to one of these channels it comes up in 16x9 for second or two and then goes to 4x3. When I hit the guide, it goes to 16x9 just before the guide comes up. It happens with both of my H20s. It is not shrinking to 4x3, it is expanding to 4x3 on my 4x3 wall screen.
