I have two R-10's and both of them had the same problem. I noticed that they stopped outputting in Dolby Digital. This occurred recently, after the new "up- grade" to 6.3e. I went into the R-10 settings, audio, Digital output. and noticed that the selection had been changed to "Dolby Digital to PCM", which I believe is the default. However; when originally setting up these units, I had set to "Dolby Digital". It is obvious that upon the recent 6.3e download, it was changed back to the original R-10 default. Dolby Digital was being recorded to the hard drive, but would not output to Dolby Digital. I changed the setting back to what I had: "Dolby Digital" and that corrected the problem. Obviously it was necessary to change on both R-10s. My reason for this post is that perhaps other R-10s have had this change when 6.3e was downloaded, and have gone un-noticed. I didn't notice right away, as there are not that many sources with Dolby Digital; mostly premium channels. When watching a Showtime movie, I noticed that the Dolby Digital indicator lights on my receivers were not lit.
