So this is what is happening: I convert avi to MPEG2 with cucusoft's Avi2DVD,and theren is't any problems there. Vid and sound ae both ok, about 40 min in lenght. Next, I load mpeginto DVLAB pro, and demutiplexit with it. But when it finishes demux a new window openinwhic says : "wrong FPS ; size 720x576 FPS:23.98 aspect: 16:9 ; to add 24 frames you need to enable pulldown first" . So I start pulldow,and when it's finished I get audio which is 4 min's lenght but vid is 48 min's. I really don't know where is te prob. Thank you for the help.
Import the file(s) (AVI, WMV,MPEG, VOB)
Output (standard DVD file format) to a folder on the HDD.
Set 'Aspect' to 4:3 (if you have a regular TV)
16:9 if you have a widescreen TV.
Set 'Standard' to NTSC (if you live in North America)
(PAL if your in the UK)
Run ImgBurn Click 'Mode' > 'Build'
Click 'Output' > 'Device'
Click 'File' > 'Browse for Folder', highlight on the 'VIDEO_TS' folder, > 'OK'
Set burning speed to 4x and click the green write button.
