Those of you who use Subler to add .srt subtitles to your mp4's may remember a while back that there was some bug in iOS where the Apple TV 2 and the iPad rendered the subtitles way too small to read, and trying to change their size didn't work. I now have a similar problem, but for iTunes. I'm on a new 2011 MBP, and the only thing keeping it from being a great experience is the trouble I've been having with iTunes problems that I didn't have on my old MacBook. Much like the iOS subtitle bug, iTunes on my new MBP isn't obeying Subler's subtitle size and offset, and as soon as I go fullscreen, they're way too small to read. For some reason, this is only happening on the new MBP, despite my MB and MBP both being on iTunes 10.2.1. I'm not sure if this is somehow related to the iOS 4.3 Home Sharing bug on the front page, but from my sample size of one it seems to be an iTunes bug that's only affecting the new MBP. I have a few mp4/m4v files for which iTunes is obeying Subler's subtitle size, but after examining every setting I can think of, I can't figure out what makes them different from the majority that don't. And all of them play properly in QT 7 Player and the way they always have QT X Player. I don't suppose anyone out there might have some ideas, or have run into this kind of problem before with subtitles in iTunes?
