You also see that TWC has done the same thing in the past and now there is a Cydia patch called FakeTWC to get past it. There is also a modification for the iO (Cablevision) app as well.
The ONLY reason I need to modify the DTV ipad app is just to ensure it works for my legitimate usage. My iPad is Jailbroken for other tweaks that I enjoy. Now the fact that DirecTV for Ipad does not even LAUNCH is a killer. I could care less about streaming video (If I wanted that REAL bad, I'd get a Slingbox or Vulkano). I just want to maintain the same functionality I had in 1.2.6 which was remote control, guide navigation and telling things to record.
I've looked all over in iFile for a similar fix for the DirecTV Nomad app, but I have yet to find anything.
I guess this is why live streaming for these channels is not available for DirecTV2PC. On a PC you have full access to it's file system. On a closed iOS device there is no file system access. I guess I doubt streaming would ever be available on a Mac or PC, despite other streaming services work just fine (Netflix, Hulu, Youtube, Vimeo, etc.)
ANYWAY....
I'm glad to see DirecTV have enough bandwidth to stream in the first place. I hope this leads to more IPTV like Video On Demand services... not just to iPads but to the receivers as well. It's a real PITA that you can't do VOD on a regular HD box. Their download first then play model is outdated. Cable VOD is so easy because you find what you want, click play and right there it is. We use DirecTV VOD FAR LESS because you click on something and then boom it goes away. You have to exit VOD and go into the Playlist to see it. While I don't mind the feature of queuing up a bunch of content to watch later, there is a bit of a convenience factor lost if you want to watch a short clip RIGHT NOW (like a music video for example).
