Thanks 2Loose. I didnt know that they did but am pleased that they do. I had tried IMG burn twice before, got picture but no sound on the DVD players but they worked fine on the laptop.... hence my amazement when Mrs BG did the same thing and this time they worked on the DVD players... she's still gloating
As Cardiac says, AVI files are a container for a video stream (xvid\divx\mpeg2 etc) and also an audio stream (mp3\aac\wav etc) and can be a combination of any of these.
My DVD player supports xvid\divx for video and mp3 (among others) for audio. So, if I have an avi file in which the movie is made up of xvid video with AAC audio, I get a picture but no sound - as you have already experienced.
Xvid and mp3 sound plays fine.
I use a program called Gspot to check out which components a movie is made from (but i'll take a look at mediainfo, cheers Cardiac).
Soooo...if you are looking for software to convert movies to play on your dvd player, ensure that you choose mp3 for the audio part and all will be well.
