Advertisements Got a notice in my Cox statement this month that said beginning mid November through May of next year Cox will be transitioning to mpeg 4 encoding. They said to check channel 1987 to make sure that your device (Tivo Bolt Vox) is compatible which I did and it was. Ch 1987 was a test channel showing CSPAN programming. When double checking resolution broadcast on ch 1987 it was 720p and didn't look all that great. When checking the regular CSPAN channel (1192) it showed that it was in 1080i and looked significantly better. I hope this isn't an indication that with the switch to Mpeg 4, that Cox will be taking the path that Comcast has chosen to down-rez all 1080i channels to 720p. Will be interesting to see what happens in the upcoming months. If anyone has any info on this change happening (or has happened) in other Cox markets, I sure would appreciate any info. My current deal with them is up in January, and I don't think I'll be renewing if it's true that they will be down-rezing to 720p.
