1 fat point deduction for soundless mkv videos - or MKV "lie" by Philips
Addendum to mkv + Audio:
AAC and AC3 ever not function. Not one tested by about 20 MKV movies played on clay. When you extract audio track, convert to mp3 and the container then feeds again, it comes. But who uses the MKV container already mp3 reinzupacken to there? About an external player, such as a Tablet PC with HDMI it comes naturally, via external 2.5-inch hard drive, which was fortunately recognized and also via SD card, no sound! AAC and AC3 are the most common audio formats in MKV and be played from my Samsung TV without difficulty via the USB input. Who advertises mkv should at least point out such gross deficits, my opinion. I hope to have helped, nice greeting.
