blu-ray to SD dvd

[bwana]

i would like to convert some of the m2ts files from a couple of blu ray discs to plain old dvd discs because my car 'only' has a dvd player (it's only a 7 inch screen so i think dvd quality will be great). trouble is, the conversion is not straightforward. these m2ts files include subtitle streams as well as multiple audio soundtracks like truehd. programs like nero vision, convertxto dvd3, and prism are choking with various errors. somewhere i read about using tsmuxer to strip out truehd. i tried that and saved the output as m2ts as well as ts but i still have problems. does anyone here have experience in this sort of conversion? (successful experience)

There is not point and shoot tool out there to do what you are looking for. You need to demux/process you BD files with eac3to (a command line tool), use avisynth to change the definition of the video and then use an mpeg2 encoder to change the format to one that your dvd player can cope with. Here I'm assuming that your car stereo only plays DVD format movies. If it supports other formats which offer better compression you should look into those encoders.

well, i found an app made by cucusoft

avconverter that's only 8 meg! it uses haali mediasplitter but i dont know what kind/brand of encoder it uses. the result at 720 x 480 is a little vertically stretched but if i check off constrain aspect ratio it comes out fine. anyone here have any reason to dislike it?
