DirecTV is mailing notices to customers about the impeding upgrade to version 6.2 of the software on the DirecTV DVR units. The traffic in message boards seems to be a pretty positive response. Faster access to the program guide, folders for TV series and the ability to sort recorded programs by title or date recorded are new features listed. A few posts on the forums indicate problems with the 30-second skip after the upgrade but these all end in successfully getting the skip put back.
On the down side it resets favorite channels so there will be more time spent getting rid of the home shopping network and it's cronies.
