Yes, do buy DM500 HD Please !!!!! By far the greatest box for money value atm. I love it, takes 50 sec to boot up from scatch, and only 20 sec to restart enigma. Dm800HD uses like 3-4 min. to start..? Had one before but sold it.
Everything works like a charm with DM500HD and Newnigma2 Image.
My DM500hd also got that problem of permenant green light. In the first two months it worked amazingly well but then without changing anything it got that permanant green light and after that your dm500hd is nothing but a piece of junk.
