Sorry if that was not clear, but I answered the first part: “Can’t play VOB’s or ISO’s.” The audio sync cannot be cured by a factory resetting in my opinion.
Now the support has answered and surprised me a little bit:
Dear Laszlo,Thank you for contacting Western Digital Customer Service and Support. My name is Nestor V.I truly apologize for the inconvenience you are currently experiencing. The WDTV does not support ISO format, you must convert the file to a supported format in order to be displayed at the WDTV. Please see below the supported formats:http://www.wdc.com/en/products/Products.asp?DriveID=735
So there’s no ISO support in WD TV Live. What the heck? Now I checked the package and true, there’s no ISO enlisted in the video formats. Anyway, in the shop I bought, it was there.
I am pretty sure the same would happen if I play the same DVD from within the VIDEO_TS folder. It must be something related to DVD features, rather than the ISO format, I guess.
