I have problems viewing JPG files which were produced by a Nikon D300, on a PS3 (firmware version 2.20 but had issues on 2.17 already). The JPG files resulted in a "Unknown format" error.
Note that JPG files from other cameras (Nikon D200, D70, Coolpix 4500, S4 etc..) work fine and that ironically, if the JPG files are placed on a CompactFlash media and inserted into the PS3, it will work fine!
JPG files were loaded on QNAP TS-109 NAS running Twonkyvision 4.4.4. The TS-109 has firmware version 1.1.5 release 0128T
Anybody else have any experience with this wierd combination? Any help is most appreciated!
