DirecTV users with combo TiVo units (in either standard def or high def) have been kind of hung out to dry for the past year or so. There haven't been any major software features added to the standard def units and the HD units only get a handful of channels (see DirecTV's HD Problem for more).
A reader recently wrote in with this story about attempting to get local current HD programming from DirecTV on his HD TiVo:
...statement(s) showing the LA/NYC HD network feeds from Direct TV are outdated (3 years old). According to Direct TV, they dropped that programming option in December of 2004. Getting network programming in HD requires waivers from the networks and according to Direct TV's HD technical support group, only 20% of waivers for HD network programming are approved [...] you may expect a 30-45 day wait to find out that only 20% of us will ever get approved!
Ever since DirecTV made it known their next DVR would be from their own subsidiary NDS instead of TiVo, everyone's been wondering when the new units would see the light of day. DirecTV sent up a few new satellites for their expanded MPEG-4 HD lineup (they say they will support 100s of channels of HD content by 2007), but current HD and SD DirecTiVo owners would have to wait for new hardware to take advantage of the new channels.
Over on the TiVo Community, it looks like official word from DirecTV is that early 2006 we should start seeing HD DVRs from DirecTV, with coverage in 12 major cities. It also sounds like there will be some sort of trade-in program for HD DirecTiVo units. As always, I'm curious what the user experience will be like compared to the TiVo devices. I've heard good and bad things about the NDS units over in the UK.
