If I purchase a Sling Box & connect it to my Directv can I watch it on my Droid.
Not yet. Sling has yet to release a slingplayer version for the Android OS, There are a few other posts here that mention them looking for Android savvy talent. I myself had it on my Q9c and do miss it. I'm hoping the Droid's sales numbers will light a fire under development decisions.
This is the bandit's life, It comes and goes and them's the breaks
There's good news coming about this question . Though i'm not sure how long i will be, but there may well be an app for that at somepoint. So the Slingplayer won't be necessary
Sometimes , It is what it is !
