I can’t see any subtitles on my Apple TV?
The Apple TV is kind of picky when it comes to subtitle languages.
To solve the problem, press and hold the play button on the apple remote. A menu will appear where you can select any subtitle track manually.
Can I add subtitles to a movie or tv show purchased on the iTunes Store or from my Apple TV?
Yes, you actually can. It works with purchased material but not rented. Apple adds a DRM protection to all the movies you purchase from the iTunes store. You will only see a gray box when opening the movie in iSubtitle, but you can still add subtitles and save the movie using File->Save as... This copy will be saved into a .mov container but it will play as usual in iTunes, QuickTime Player 7 (not QuickTime X), Apple TV and so on, but the subtitles will be there. If you dislike the DRM protection as much as I do I suggest you send an email to Apple with your complains. Download QuickTime Player 7 from http://support.apple.com/kb/DL923
Update 2011-11-01. When using this method there will be no sound in iTunes 10.5. When you sync it to your iDevice or stream it to an Apple TV everything will work as expected.
Sometimes when exporting I get an error saying “Export failed: Caught an exception.”
iSubtitle uses a little helper application to handle the video encoding. If the communication between iSubtitle and the helper application is broken due to another application locking or stalling the system that communication line is broken. Launch Activity Monitor from your Utilities folder and see it something weird is going on in the background. Rebooting your mac should also help.
When I try to open any movie iSubtitle crashes? I’m running 10.7 Lion!
It seems like the 3ivx QuickTime component isn’t working with 10.7 Lion. Please remove all 3ivx files from your home/Library/QuickTime and /Library/QuickTime folder and relaunch iSubtitle.
Please consider removing other obsolete QuickTime Components: FFusion, Xvid Delegate, 3ivX, DivX, DivX Decoder, XviD, msmpeg4v1, msmpeg4v2, AviImporter, EX_M4S2, Casio AVI Importer, AC3 Codec, and MatroskaQT.
How do I work with AVI and DivX movies?
Download and install Perian.
I can see video but I can't hear any sound?
The movie may have AC3 audio. Download and install Perian.
How do I work with Windows Media (WMV) movies?
Download and install the Windows Media QuickTime component Flip4Mac.
How can I change or remove the semi-transparent background from the subtitles?
No, there's no way to customize the subtitles cause it's all up to the applicaton/device how to show them.
The same subtitles looks completely different on an Apple TV and an iPhone for example.
Encoding is so sloooow. How do I make it faster?
Get yourself an Elgato Turbo.264 hardware encoder and save lots and lots of time. It's fully integrated in iSubtitle.

Encoding with the Turbo.264 is slower than I expected. Why?
Make sure you connect the Turbo.264 to an USB-2 port. It doesn’t work with an old USB-1 port or hub.
iSubtitle doesn’t seem to recognize my original Turbo.264 dongle anymore. How can I fix this?
Download and install the latest Turbo.264 application for your turbo. Start the Turbo.264 app to install the components. Just to be sure, Run Disk Utility and Repair Permissions. Reboot! It should be working as expected now...
When I try to export a movie I get the error, “The movie contains an incorrect time value”. Why?
The movie timetable is corrupted! Some old version of FFMPEGX was famous for corrupting movie timetables this way. Unfortunately there’s nothing to do to fix it.
