Recording issue of AVI files to DVD-R

In my personal computer I have saved video files in Audio Video Interleave (AVI), watching on it and sound works perfectly. Even in my laptop, phone, play station sounds work great. However, half an hour past when I recorded the AVI files into DVD-R the sounds it is not working. I did the proper set up of the DVD-RW and all the drivers even the proper codecs, I was also using Nero then suddenly sounds gone. I don't have any idea of what is going on. Please help.
