I'd like to play an AVI on my Sony BDP-S186. The user manual states: Supported Codecs and File Types: including Xvid (.avi) (http://pdf.crse.com/manuals/4290282312.pdf - in German). I'm trying to play the file from an USB stick. The video file's codec is MPEG-4 Video (XVID). The device says "Die Datei ist verfälscht oder unbestätigt," which means that the file is corrupted.

Sometimes it works for AVI files, sometimes it doesn't and I actually do not know what's the reason for the issue. The issue seems to be well known by the internet, but I didn't find an appropriate solution for now. This forum deals also the issue: http://www.cczwei-forum.de/cc2/thread.php?threadid=6317 (in German)

I'm buying the capability of playing files with that format/compression and not the capability of not playing them.

I would also be interested in the legal side of this issue. I don't think the cause for not playing specific videos is caused by copyright protection or anything related, even if Sony qualified themselves always for being a bad example of copyright protection guards.

I changed the file system on the USB stick from FAT32 to NTFS. The video playback works now.

  • So your files were bigger than 2GB, and were broken when you tried to put them on FAT32? Commented Apr 11, 2015 at 11:52
  • No. Usually the video files I tried to play were around 700M, every file worked on the computer and only some of them worked on the Sony. After changing to NTFS I did not experience this problem again so far.
