The problem may not be related to file format. As long as you are encoding in dvd-video format (mpeg2), there may be another reason why they won't play on some standalone dvd players.
1. Some (usually older) dvd players just won't play any DVD discs other than commercially made ones (the disc recording technology is completely different). This is most likely to apply to dvd players which are older than the home dvd-recording technology we now take for granted.
2. Some dvd recorders will play home-made movie discs, but only if they are the DVD+R type. While some others will only play the DVD-R type. Some can play both, but I think DVD+R is probably compatible with more players compared to DVD-R.
