I had posted about my HR20-700 running sluggishly prior to the latest NR and other reported the same thing. The last NR seemed to have alleviated the issue for the most part. Fast forward to last night, the system was even more sluggish than ever. I was watching The Pacific and could barely get the system to come back from pause. There also seemed to be a lot of drive activity. I started watching the playback with about 5-10 minutes left in the recording and the issue continued even when the recording was complete. I haven't had much chance to troubleshoot the issue (i.e. restart the unit). Has anyone else noticed anything?
