Tanks to manuals, I finally be able to authorize mpeg2 and burned with Nero on CDR, since DVD writer is still way too expensive for me.
My PC was able to play it from DVD ROM drive with Inter Video DVD software just like it played commercial DVD - ok, quality wasn't compatible, i know...
However, my cheap set top Lasonic DVD player won't play it.
It has no problem playing MP3 CDR and audio CD which I made from mp3 on regular CDR.
Is it DVD player problem or something was wrong during the procedure?

Thanks for you comment and reply.
