I apologize if this is a dumb question. Just received V4.03 upgrade from 3.66 HGTV shows different programs on SD and HD. Now when I enter Channel 112 (HGTV SD) It displays the HD channel instead (same as Channel 9461. How do I get to the HGTV SD channel instead?? The only way I have found is to go to the guide and manually select the 'other' 112 channel. Normally being sent to the HD channel would be fine but there are occasionally different programs on the HD and SD channel.
