I recently got the 5900 and did the upgrade with no problem. Connected to Sammy DLP via DVI set @ 720p. During playback on 3 different DVD's the appropriate closed captions for the scene suddenly came up on the display. I rolled the disk back each time and replayed and it didn't happen again (nor did it continue long). Has anyone else experienced this? If so, is there a known fix. It's just plain weird. I haven't contacted Denon re: this matter nor have I found anthing noted anywhere online. Opinions? Facts? Experiences?
