Reboot after IOS 4.1 now takes forever

Question

Ever since updating my iPhone 4 on Wednesday, my phone now takes 2-3 min. to reboot after turning it off. Anyone else seeing this happening with theirs? I'm going to take mine to my AT&T store today to see if they know why this is happening and why I haven't been able to access the data network since the update either.

Yup. This is a known issue but it's not known to that many since most of the customers get all their content straight from iTunes. There's only ONE way to get the non-iTunes HD MP4s to play. When you are staring at the blank screen, waiting for the video to buffer (which for the majority of the time, will never happen), press Down on the controller to pull up the timeline with chapter marks. Now, press Forward to skip chapters. With the original 4.1 update, you can skip all the way to the end of the last chapter, give it a few seconds, and then skip all the way back to the beginning of the first chapter (same chapter timeline, but you press Back until it goes to the start of the first chapter). With the recent 4.1.1 update, it's a little trickier. When you skip all the way to the end of the last chapter, if you don't immediately skip back, it will take you back to your videos list because it registers as you having finished watching the video. Now, keep in mind all of this takes places on the timeline with the CHAPTER MARKS.
Second thing, be sure you have chapter marks set on the MP4 file or else the chapter skip workaround will not work (since there's no chapters). You can most probably use any metadata utility you wish to set the chapter marks but I personally am using iSubtitler. I also set the chapter marks for every 10 minutes.
I don't know exactly what has changed since the original 4.0 firmware on the ATV but it has messed up the buffering for large HD non-iTunes purchased videos.
