Is there a full description on what the issue is? Or is there a list of known-issues of DM500?
I am considering to buy a DreamBox, but I can not decide which model to buy, since DM500 is much cheaper, I think I would try DM500 if there is no critical bug.
However, recording is the most important feature for such an open-source supported receiver. If it can not do recording, I can not find any reason not to buy a "normal" receiver.
