you have helped me so far - see if you can sort this bit out. i have done everything you said to convert my avi to mpg using the programme you suggested and split it also using the programme you suggested and burned to disk. when i play the disk the sound is there for just 20 seconds and then goes off -picture is fine. if i playback the avi version on my pc the sound is there - but not on the mpg disk version. any ideas from you wonderful beautiful clever people???thank you for reading my message, again!
