Comcast HD changes ..anybody know what they are doing..??

From TIVO

You may have received a letter from Comcast informing you that they were upgrading the way they deliver HD channels on their XFINITY TV service. Some digital converters (cable boxes) will need to be upgraded to models that support the new HD platform. This is scheduled to occur in early November.

Please note that this will not impact your TiVo BOLT™, TiVo Roamio™, TiVo® Premiere or TiVo HD DVR. You will continue to get all your HD channels - no action is necessary
