I've been seeing this for several updates now... After an upgrade, RTVHD seems to delete all shows from the homescreen and then starts adding them again but with all the checkmarks indicating that they have been watched are gone.
The bookmark files are still in the directory, and if you look at the description of the show, I can see that it is reading them because it will display the last day and percentage watched which comes from the file.
This an annoyance because I have about 800 archived shows for series that I want to keep reruns of for watching in the future kind of like when people buy DVDs of old seasons for a show.
How do I get my checkmarks back short of play each and every show for a few minutes?
I've added a threshold for the watched status icon. Most likely that is all it is.
If you go into Recorded TV HD -> the wrench icon -> "Menu Strip, Recycle Bin & Other Options" -> "Other Interface Options" and bump down the percentage really low (like 5%) and the checkmarks should all come back.
You can then play with the percentage later if you want.
