Here are some modifications I've made to the Digitel+ HT8400 PVR firmware (April 2012/1.02.3A). Unfortunately, I wasn't able to crack of the one checks it makes, so before I go to the trouble of creating instructions for how to load it into the unit (you'll need a null-modem cable), I'll see if there's any interest first.
