I've had my HR-21 for a little more than a week now. For a day or so I was able to make category only keyword searches using a space as the keyword, but this hasn't worked since I received 0x255. I can no longer 'continue' until I've entered a non-space character in the keyword field. Searches using only CCHAN, etc, do not work. I've tried everything I can think of as a workaround with no success. I've been pouring over this forum and the directv official forums looking for any discussion of this but have seen nothing. With my TiVos I was able to set up wishlists for say science fiction and comedy movies but I have been unable to reproduce with this the HR-21 autorecord searches. Any ideas? (Please don't suggest using HDTV etc as keywords. Not really an acceptable restriction).
