I agree, there is no way I will get another DLink device if this is how it goes with them. A year later and then the new device will cease to work as well?!
I'm looking in to run TVersity with my 520 and/or PlayOn, which both hopefully will run fine for a while. At the time they don't work on the 520, and I still haven't gotten any updates from DLink, I will look in other places for a solution and most likely won't ever look back for a DLink solution ever again.
I hope all DLink officials understand the importance of this!? My, and I'm sure everybody elses, previous experience with you will affect me/us 110% for any future purchases! How well you handle this is your biggest advertisment for both your current and new customers!
