Hi All, I've finally had some time to work on a major update of MKVtools and since I know that there are a few users in this forum, I thought I'd see if there are any requests for improvements. I've already incorporated some of the most commonly requested features in the latest beta: MKVtools now accepts any type of video file that mencoder can process (avi, mp4, ... but not VIDEO_TS folders). So, for example, you can now convert an avi file for use on your ATV. 5.1 AC3 and 5.1 DTS is now converted to 5.1 AAC. MKVtools used to mux 5.1 AC3 audio into a file that I hoped was playable by ATV's but I never was sure if it worked for you guys. Hopefully this will be more successful. You can now "burn" external subtitle files into the output. Improved presets in a "Quick Conversion" box with one button conversions where MKVtools guesses at the best settings for the selected output hardware (DivX DVD players, iPod, Apple TV, PS3 for now). So you don't need to request any of the above. Since I don't have an Apple TV, I'm just guessing at your needs (e.g., would soft subtitles be useful?). So if you would like to see anything else added while I have this window of time available for programming, let me know either in a post or at email@example.com. I'll just be tallying the requests, so unless I need clarification you probably won't hear back from me. Also, if you have the time and want to get MKVtools to be useful for you, feel free to send any feedback about the beta to firstname.lastname@example.org. Your old registration code will still work for all of the betas as it will once the final update is released. The big Apple TV question I have is whether or not the trick of changing the AVC profile level to 4.1 works for you as it does for the PS3 and xbox. Cheers and thanks in advance for any feedback.
