Thank you to the folks that have guided me to almost the finish. I did get the Guide data to load after reading Yaobling's instructions. Unfortunately, this success prompted me to make OTA recordings, now that I could, but trying to view these recordings makes MC crash when, at the end of the recording, I click the square box (next to pause) to close the viewer. For quite some time I have been using MC to view all my recordings that I have been making in the HDHomerun DVR, and then JR works flawlessly, without crashing when I close a recording.
I got JRiver Media Center version 21 several years ago to replace Windows Media Center because my computers had become Win 10. I upgraded yearly until now. Presently I use MC (25) for all my Audio needs and for viewing all my video. I need Closed Captions and these are absolutely the best. I really want to get the DVR to work properly, so getting that done will become my new focus. Now that I have an EPG I will be able to again try to figure out why recordings come out perfectly on the HDHomerun DVR, but are blocky and break up (and crash the program) when recorded in JR. I have discussed this with the tech folks at Silicondust, and they suggested that there could be a conflict with their DVR program. Uninstalling it from my NAS broke all television recording for several days and I had direct orders to get it fixed, which is the reason for the delay in reporting back on EPG123 progress.
On a high note, EPG123 is just as good as I remember it from when I installed it into WMC. I am an old movie buff. The movie descriptions from 123 in WMC were far superior to the normal ROVI data. Even in MC, comparing an old movie description obtained from Schedules Direct using the embedded mc2xml in MC yields about half the information that comes from the SAME Schedules Direct source using EPG123. The only thing missing is the movie rating, which was present in WMC. From what I understand Schedules Direct uses Gracenote data, which is also used by HDHomerun DVR, which does have movie ratings. I intend to mention this to Gary to see if we can get it included at the end of the description.
I will try recordings again with HDHomerun isolated from any contact with MC and see if I find joy.
Thank you,
Steve
