losing quality

[sky_dave]

i dont want to losing quality when demuxing video and audio streams.
What's the best demuxer?

[LIGHTNING UK!]

Demuxing doesnt effect quality. Its the conversion/reencoding bit that does.

Therefore, any demuxing tool will do.

How can i check the quality of the movie?

what the heck does that mean. Are you looking for the bitrate?
