sub help

I have a problem with the sub. I always receive a blurry sub no matter which programs I used (DVD decrypter or DVDx). The first time I had a perfect sub for the Lord of the Ring, but then the problem appear after that. Please help! I don't know why this happened.

I presume that your LOTR subs turned out great because they use bitmap subs, not player-generated subs.

Subtitles are never player-generated ... they are stored on DVD as BMPs and the standalone displays them as an overlay. On some DVDs, you have subs that are hard-encoded into the image, but that's a completely different story. @shadow10: what exactly are you trying to do? Burnt-in subs? Selectable subs? SVCD?

What I did is that I used DVDx to copy the movie to SVCD, this including sub. Is there a way to correct the problem? I read that sub are stored as bitmap, then can I just copy that and imbedded it to the movie. If yes, how can I do it?

I have no experience using dvdx ... did you try checking the "Original Colours" option? Also, I have no idea how dvdx extracts the subs. ALternatively, use a tool like subrip to extract the subs from your vobs and use (win)submux or I-Author to add them as BMPs to your video. You will end up with SVCD- or CVD-style subs - these are selectable (you can have up to four subtitle tracks) and you will need a standalone capable of displaying them (there are no software players supporting selectable SVCD subs). vcdhelp.com will give you an idea if your standalone supports such subs ... Alternatively, you might consider using dvd2svcd - it will do either burnt-in (like dvdx) or CVD/SVCD-style selectable subs for you.
