Direct - not currently
Dish - very very few hacks that work and it is the kind of thing you have to stay on top of day after day.
Nothing like it used to be with , hack a card and watch for months.
How do I know ? I worked for GE/RCA when they were the makers of the directv receivers . It took many revisions but it is finally to the point where the entire system is closed. People cannot get datasheets and programs to the cpus, the chipsets, or anything , so if they have to hack it they have to reverse engineer a entirely closed system, which if you have attempted that , you know that is a sob.
