Hi, I authored my dvd with dvdlab pro 2.0, with subtitles and then next, I edited the ifo files for 2 audio and 2 subs, chinese and english. But when I play the final product on my dvd player, the subs doesn't show at all. I can click on the subtitle button, and it'll say english or chinese, but the subs won't show. Can anyone pls help me? I don't know what I did wrong. Thanks.

Edit: Forgot to mention that the subtitles showed perfectly fine on my computer with powerdvd. I don't know what went wrong. ><
