I don't know if this has been mentioned, but I just recently noticed that although both HGTV HD and Food Network HD channels are mapped down to the SD channels, they are not simulcast. Has this been the case for longer than I was aware? While it is true that the content may be virtually identical, the HD channels are airing different programs at different times. This is opposite the Dish practice of mapping down only simulcast HD channels. If there is going to be a difference of airtimes for the same shows on two different channels, then I, for one, would prefer different channel numbers for the HD and SD channels.
