iPod users who would want to have subtitles added to their movie files should take a look at this great find: Submerge. Bitfield's Submerge lets iPod, iPhone and Apple TV users merge a separate subtitle file (either .srt or .sub file types) with a movie file that will still be playable on an iPod, iPhone, or Apple TV.

Here's the list of features that makes Submerge a sweet package:

• Make subtitled movies that are playable on your iPod, iPhone, Apple TV, in iTunes or in Front Row.
• Add subtitles to almost any visual format like mov, avi, mp4 etc.
• Supports the major subtitle file formats like SubRip (.srt), SubViewer 1 & 2 (.sub) and MicroDVD. More about subtitle formats...
• Support for the Elgato Turbo.264 hardware encoder for faster compression.
• Force aspect ratio to 16:9 or 4:3 to use your monitor space more efficiently.
• Watch subtitled movies in fullscreen without leaving the application.
• Merge multiple movies together using simple copy and paste.
• Localized in English, Italian (by Vella Bruno, www.pyxart.it/macsw), French (by Ronald Leroux), Finnish (by Arto Vartiainen), Spanish (by Clapp!, http://clappin.net), Dutch (by Lex van der Helm) and Swedish.

The program is quite easy to use: just make sure you have the needed .srt or .sub files handy, tweak the settings in the Settings Drawer (even change the fonts), and you'll be ready to go.

Submerge can also do more than add subtitles, however: it can also adjust the aspect ratio of the movie file to better fit the screen. This function will prove to be very useful to users of the new iPod Nano.

If you're interested in using this program, do take note that Submerge isn't freeware like TubeTV; you can get it for only US$ 9 but if you're leery about purchasing the software outright you can always download a free trial version in its official site, which is linked below.
