No, gusto ko nga ung technical part eh. Please show me.
Is it the pride I scratched? Sorry no offense meant..
m2ts(Mpeg2/4 transport stream)container was designed by Sony(and other companies i think) for HD videos using AVCHD packets. They called it BDAV MPEG2 transport stream. It's just a container, meaning you can have different video compression type. You can use mpeg2, h.264, vc1 as your video encoder. It can be HD or normal quality.
m2ts transmits video/audio frames in form of packets, not necessarily 1 frame/packet. This is in contrast with Program stream which is continuous video/audio frames. Transport stream has error correction while program stream does not. Kind of HTTP/FTP analogy hehe!!! A frame is a full image(for progressive only, in an interlaced type, frame is either odd lines or even lines) with corresponding audio frame (if it has audio).
so in essence, you are just ripping the main video/audio part(not including the extras, menus etc..) of your DVD. The format/compression of the video/audio packets remains intact. So you can expect that the quality of your DVD is the same as your copy of m2ts. This only holds true, if your ripping software does not transcode the packets into another format.
