TB:
First, which DVD player do you have ? Not all DVD player can decode SUBS.
Second, if doing subtitles the I-Author way, remember to use "I-Author parameters" in subrip097b.
Third, you can also use the "Submux" method. With submux you can make Phillips style subs or CVD Style subs...Check which is compatible with your unit.
Fourth, If neither works then you can make permanent subs with Virtualdub...
For "submux" info look this post...
