Lägger till lite info.
"All of you pulling your hair out about thinking the GT10.1 cannot play HD video need to step away from the keyboard, make yourself a cocktail and take a deep breath. It will be okay, I promise. The GT10.1 can and does record and play HD video. For those of you trying to play .mkv files please understand that Matroska (.mkv) is nothing more than a container (think of it like a wrapper around your favorite candy). Inside that container are files for audio, video, subtitles, metadata, etc. The audio and video files are compressed into some format (codec) that can only be played correctly if the device doing the playing has the decoder to read said codec. Tons of people are having no issues playing 720p .mkv files simply because the audio and video codecs in that particular file are supported by their player. The most frequent video codec in .mkv containers is H-264. Audio on the other is typically found in AC3 (as this supports full Dolby Digital surround sound) but can be found in many different codecs. So, if your .mkv video file has H-264 video and AC3 audio but your player does not support either (or both) of these.... then your options are to transcode the audio or video to a supported format (which can be done while maintaining the .mkv wrapper mind you) or find a player that supports the code in your original file. Now, be aware that if you transcode, this results in exponential data compression and thus loss of data. So, audio loses its fidelity and video loses its clarity. Think what happens to the quality of an orginal letter or document when you make a photocopy of a photocopy of photocopy. In order to avoid this you must create the encodings from an uncompressed wave form (directly from the DVD or BluRay) and then place those in wrapper (like .avi or .mkv etc). This is the process of ripping a DVD.
None of this is new. It has been the case LONG before the GT10.1 was released. The perceived problem is exacerbated by people thinking (at no fault of their own) that .mkv (Matroska video) is simply some magical file format that delivers movies in full HD goodness. Its like everything else in the audio/video world on computers, it is always a function of codecs and decoders. E.g. just because I can speak German does not mean you understand me simply because we are having a conversation. You must also understand German.
Sorry for the diatribe, just wanted to clear the air on where the issue lies here. I do think that VLC will be solution for most everyone out there not knowing how to or not willing to play around with encoding audio and video. I know how to do this and I don't even want to do it. VLC should offer support for the popular .mkv file components out there and (most of) our woes will be over. Lets just hope VLC drops there app sooner rather than later!"
