I've only had it installed for an hour or so on my 60 GB 5G, but so far so good. It does appear to fix the endless star ratings screen bug. I haven't tested any videos yet, but can't comment on its affect on the old video playback issues anyway, as I've been using more recent versions of iSquint and Handbrake which already resolved those playback issues themselves - I've no old conversions to test with. I like the new volume limiter option. Note that you can set this with or without a code lock. It's useful in two ways for me: allowing my 5 year old to listen to my iPod, as he so wishes to do, without having again to worry about him changing the volume to too high of a level. Further, for me, I can set the limit to what I consider to be more than loud enough, and then I never have to worry about accidentally bumping the volume up to painful levels (which I've done it on a few occasions when attempting to scan forward or set a star rating via the scrollwheel). Since I never have to set the volume higher than halfway at the most anyway, why not limit it to halfway? I can easily enough change the max if needed. Cool feature - thank goodness for "frivolous" lawsuits. :)
