4 digit to 2 digit HD channel transition

Watching TV just got easier An important update on channels 1000-1950 Hi Paul, On Wednesday, December 15, we’re removing duplicate HD channels currently found on channels 1000-1950. This means you’ll watch your favorite shows on the corresponding 1,2, or 3-digit channel. For example 1034 = 34. Not to worry, no programs are going away. We’re only making the change to simplify your viewing experience. Your favorites and parental controls won't be affected either, so you won't have to do anything. Check out our latest channel line up here. Using a DVR? Double check to make sure your recordings haven’t been dropped after Wednesday, December 15. If they have, you’ll need to reset them to record your favorite shows. Power On Channel? Don't forget: If your Cox TV auto powers to a 4- digit channel, it'll need to be reset to a 1-3 digit channel. For example 1006 = 6. Questions? Chat with us anytime. Thanks, Cox

This is called "re-mapping" the virtual channels.  It probably will effect t any presets on your equipment.  For example, if you're set to record channel 1005, you'll need to change the recording to channel 5.  If you have a customized view of a channel guide, you'll probably need to adjust it.

You were receiving the "digital companion" frequency-channels all along...just not using them because they were probably a lower format.

In 2009, if Digital TV was the future, providers should have originally mapped the SD channels to 1000+.  What difference would it have made?  We were already in its understanding phase.
