how do i make my tv automatically adjust to the correct aspect ratio?

TomCat4680

I have an Insiginia 42 inch LCD HDTV and a Motorola DCH3416 HD / DVR digital cable box with Comcast Digital Cable connected by an HDMI cable. My tv has a button to switch the aspect ratio and I have to manually select the right one. The settings are normal and wide (and zoom and cinema, i dont know what they're for, they always make the picture too big to fit my screen), so if i want to watch an HD channel I have to switch it to wide, and for SD channels I have to switch it to normal and this is quite frustrating. How do i make it automatically pick the right aspect ratio?

Also I can't switch closed caption mode using the TV's original remote when using the HDMI port. It says "No CC information available" when I know the channel DOES have closed captions.

Go into the comcast cable box's set up menu and set HDMI to 16:9, and SD to off (not 480i or 480p). Then be sure your tv is set to 16:9, when you change channels, they should automatically adjust to the correct size. Just be sure you don't have any zoom or other adjustments selected on your tv's remote. That should do it.

Can't help with CC, but there are posts about it, just check your cable company's discussion site at the top of main page for info:

Just a SWAG here but have you checked the cable box ?
Mine has settings that tell the cable box what to do with the signal that it sends to the TV. I set mine to send the signal as is and that seems to work fine.
My TV and cable box are both different than yours so YMMV.

Can this be accomplished with a D* receiver as well. I have Panasonic plasma and I always have to switch between just mode for SD (no bars) channels and full mode for HD channels. It is an HR21-100
