Since as the other thread seems to have gotten lost in transition, just want to mark that 6261 seems to fix the problem of being unable to download 4k bundled movies.
Only thing’s left, and I didn’t try this before: free 4k content (marked as “free to watch,” not “free with ads”) seems to be perpetually stuck on analysing when the selection box is set to H.265, e.g.:-
https://athome.fandango.com/content/browse/details/Evolution/953957
The only slight annoyances that are left are the DoVi selector gets populated with H.264 options when DoVi isn’t available for a 4k title, and the download indicators in the “downloading” window. On the plus side, the updated download engine also seems to affect Vudu, so downloads are noticeably much faster!
