I just got the iPod touch (32gb). Got a bunch'a movies on my computer (avi, mkv). Is there a good converter that is FREE for those file types? i know visualhub was popular but was like $30 but according the site it no longer exists? is that correct? I downloaded iSquint and am currently using it to convert avi's to mp4, but i was wondering if it will convert mkv? is iSquint the best out there right now?
