It has been quit a while since a firmware update has been released for this unit.I am sure you are aware that there is a list of issues with this player that need to be addressed.I have two of these units and am beginning to regret my purchase.The player itself seems to have great potential and does do a lot for the money but the seeming lack of support does not instill confidence.
The biggest example is the MP4 sync issue, the unit is advertised as having the capability of playing MP4 video but cannot without a 4-6 sec delay on the audio.This issue has gone unresolved for almost a year !!
I suggest you start to check out some related forums as your products reputation is dwindling in comparison to your competitors
