LinkStation Live, DLNA permissions problems on some TV

I own a LinkStation Live 3TB presenting the following problem related to DLNA: all folders are seen and work just fine in all devices but one (LG 42LE5500) where, when browsing "Videos", only some random file is seen by the TV's DLNA client. It worked fine but now won't let me browse the folders anymore after I did some changes with folder restrictions in the NAS. I already tried changing the folder shared on DLNA, restarting NAS, shutting down, re-initializing the DLNA database, etc. I'm pretty sure whatever's happening has to do with folder permissions, but I don't know what.
I've noticed that folders under the DLNA share show the following "particular" permissions on Windows 7:

admin (Unix Group\admin) -> Read and Write
Linux User (Buffalo\admin) -> read and write

If you remove permissions on the DLNA share entirely, what happens? If it works on other devices, does the device in question have the ability to update firmware?
**A single copy of data, even on a RAID array, is NOT a backup! Hard drive failure is not a question of IF, but WHEN! Don't take my word for it, take Google's!**

Eastmarch, I tried without permission and with permission (access restrictions on the shared folder), and the result is the same. The other devices don't seem to care about permissions: for them it always works fine. But this -older- LG smart TV is crazy since I changed permissions for the same time.
I thought maybe the problem is that I moved folders from one shared folder to another ("DLNA" to "Videos"), so the folders kind of "dragged" permission with them, but then I moved them back and...nothingness.
Then copied and pasted all of them. That's when it worked for the 1st file, but after doing the bulk paste it went back to nothing.
Unfortunately the LG has no firmware upgrade.

Well it's pretty clear that the problem is specific to that device. You might try removing and re-adding the share, if there is such a function on that TV.

Yesterday I had a technical revelation/dea and I tried something: I copied one folder at a time from the previous public DLNA folder to a new one, checking after each folder was there if it was still working.
To make things short, I discovered that a specific file was breaking everything, and whenever I added it to it's subfolder inside "Videos", things would go bad.
If I removed it, automatically I could see all the folders on that TV.
So I just didn't copy that one and everything's back to normal!

Out of curiosity.... what was the file name, or at least the extension?
