I have two 21-700's. Both connected via HDMI. 1 directly to a Sony Bravia LCD, the other to a Sony ES receiver, then to a Pioneer Elite Kuro plasma. The one direct to the Sony is functioning perfectly. The one to the ES and Kuro has an issue with recorded playback. Every 15 to 20 minutes, the playback freezes for 20 to 60 seconds, then resumes on its own. No remote button controls are accepted during the freezes. I re-downloaded 0290 and this has minimized random reboots, but I still have the freezing. I don't understand why they do not just re-issue the previous stable OS while they get this release fixed. Getting a little tired of being the software QA/QC department for DTV (since they obviously don't have one). Have any of the calls to support mentioned in this thread yielded an expected resolution date?
