Why don't the following channels filter into appropriate filters in the guide (ie movie & events, sports channels, etc.: ABCFHD HALLHD HDNM UHD HGTVHD COMHD HDN WGNHD Is it due to some contractural deal between Directv and the channels or just some oversight? If its not intentional most of those channels have been around a LONG time. My DVR's are the HR20 and 21. Do newer versions also have the same apparent flaw? Also, do the newer DVR's allow for more than just 2 favorites lists?
