I know this thread is about video (which still doesn't work; as a matter of fact, it seems to have gotten worse), but here's some 4-1-1 on the music crAPP (from the answers.microsoft.com forum):
I for one can't figure out this music thing at all...three solid days and nothing is working. Well, nothing that's permanent. Twice I've gotten the music the way I wanted only to see it go bye-bye the next day.
Recently I tried something a bit different: I made hidden files visible and unprotected system files. I then connected the SD card directly to my PC and used File Explorer (Win8), to transfer my entire Metallica collection. While the file DID move and some even HAD their album art, I've noticed a very aggravating issues that pops up all of the time: Death Magnetic somehow transforms to "Seven Songs for America" by Bergevin Brothers Music. The album art is that of a blue background with an American flag, but the album itself, as well as all of the tracks (10, the same number as what's on the DM album), are listed as 'Unknown', though they will play the correct song (i.e. track 4 (unknown here), will play 'The Day That Never Comes').
And there's this recent behavior when the music on the SD card couldn't be deleted at all! Not through File Explorer and not through the app. Actually, the app will tell me it has deleted the files, but when then going back to the main screen, the music is still there. I rebooted the phone numerous times and did the whole 'remove SD card' thing...nothing worked. But then the app suddenly told me 'oops- there's an error and we can't delete the files'. What kind of horsesh1t is this? If I had written sh1t like this in school, I would have received an F. GET WITH IT MS/NOKIA!!! THIS ISN'T ROCKET SCIENCE!
EDIT 1: I was able to transfer the Metallica collection using the WP8 app and it got it all right. Of course, after the transfer was done, I let it sit there for about an hour before checking on it, so I dunno if that had anything to do with it.
EDIT 2: I forgot to mention something about transferring music. Earlier I wrote how I made visible hidden files and unprotected system files on my Metallica collection and the effects of doing so. I also did a test on what would happen if I re-hid and re-protected files. I did this on my Iron Maiden collection. While all albums and songs moved over, none of the album art made it.
EDIT 3: OK, given the sucess of using the WP8 app to move one set of music over, I then tried to do a single song from another album. The song moved, but the art did not. HOWEVER, and this makes no sense, the album art for that SINGLE SONG is being displayed in the WP8 app, but NOT ONE for ANY of the Metallica albums!!
EDIT 4: Now this is just getting STUPID. Let's recap here for a minute:
1. All Metallica albums, songs, and album art (using the WP8 app), moved over to my 822 successfully.
2. In the Music section of the WP8 app, not one single album art is displayed anywhere for any of their albums.
3. Transferring a SINGLE SONG (Thunderstruck- AC/DC), resulted in the album art missing from the phone, BUT IT IS DISPLAYING IN THE WP8 APP.
4. Transferring Ten by Pearl Jam also failed to get any of the album art over to the phone. BUT, in the app, the album cover IS THERE AND DISPLAYS THROUGHOUT! (the Metallica collection simply displays a generic music icon). Whoever wrote these apps and tested them...YOU'RE FIRED. (h3ll, given employment history at MS, maybe they were!)
EDIT 5: I've noticed another very strange set of behaviors with all of this:
1. I can delete all music, albums, songs, from the device via the app, but if I wait a few minutes, some or all of them will reappear! Other times, though the media is deleted off of the device via the app, the device still shows the media there! On a related note, though neither device nor the app show any media on it, when I open File Explorer and browse the SD card, THEY ARE ALL STILL THERE!
2. If I try to delete the files from the SD card manually, two folders (the folders for the collections of Iron Maiden and Metallica), WILL NOT ERASE! The OS claims that they are write-protected! HUH?
MS- are you hearing this?
