"a problem" doesn't tell us much!
I didn't know what the problem was exactly but I think it may have been finger trouble. I had another go yesterday and managed to shift stuff from the old drive, connected to the front USB, to the new internal one.
When I press "Media" & "OK" I see Three USB drives in the main list, but I guess that must be down to me updating the packages and installing some I didn't have before?
I am now unable to successfully download media to my PC, via the web IF, since updating packages. They are downloaded but are unreadable and appear to be still encrypted.
Media Info reports the following.
Complete name : C:\Users\Peter\Desktop\The Doctor Blake Mysteries_20170813_1959.ts
Format : BDAV
Format/Info : Blu-ray Video
Format profile : No PAT/PMT
File size : 956 MiB
FileExtension_Invalid : m2ts ssif
Is there a package I've left out, as I used to be able to download without the encryption?
