Not that I think it would have any impact on the company, doesn't Murdoch still own a large chunk of DirecTV? I know Liberty now has controlling interest, but that doesn't mean that Murdoch isn't still heavily invested in DirecTV. Either way, like I said, I can't imagine this would do anything to DirecTV, or any other companies that News Corp owns, like Fox News - FNC isn't going to fold just because the parent company acted like this.
What you may be remember is that I do believe Liberty has some interest still (I didn't go back and look), but they no longer hold Controlling interest.
Basically, DIRECTV spun off from Liberty and are now a entity all their own.
