Advertisements (FYI, I have also posted this at videohelp.com.) Hoping that one of the experts can point me in the right direction. I have been searching this and other forums, but still haven't been able to come up with the solution. Might have learned a little about codecs and containers along the way, but I am definitely a newbie. My situation and end goals would seem pretty simple: I have a bunch of home videos shot on m Sony HDR-SR7 Camcorder that I have transfered to my computer. I also have a couple of Tivo Premeirs in the house and would like to transfer and/or stream those videos to my Tivos. The Sony packages the files in a file with a .m2ts extension. tsMuxer 1.10.6 reports the following about the files inside the container: H.264, Profile: Main@4.0 Resolution 1440:1080i Frame Rate: 29.97 AC3, Bitrate 448 kbps, Sample Rate 48 Khz Channels 6 While I have used Pinacle Studio (v 12 first, now v15) on ocassion to manipulate the files such that I could use Tivo's standard app for viewing playing the videos, it is a bit tedious and it is never clear to me if I am doing some re-encoding that would result in a loss of quality. I would like to quickly and without loss of quality, remux(?) (new word to me) the files to be able to see them through my Tivos. While I might go back later and use Pinacle to combine files and pretty things up (hopefully also without any loss of quality), right now I'd settle for getting my unedited files from my camcorder accessible. Have recently discovered Streambaby (streaming application for Tivo), and I definitely prefer the streaming approach over the pull approach in the standard Tivo App. Have also been playing around with tsMuxeR and Yamb/Mp4box based on a little information that I found on other sites. (Mostly here: new user - can't post link). Using TsMuxer/Yamb without changing any defaults, the resulting file has the video playing at half-speed (I think do to some mishandling of the interlacing?). Doubling the frame rate in Yamb for the video file results in very jerky video in the final file. Any help would be much appreciated. Thanks.
