Well this isn't a reason why but should at least be a way around it. Every now and then I will notice corrupt "blocks" in my avchd footage (almost like it was encoded at a low bitrate). What I have to do is open it in AE and re-render it out again. I think I might have even been able to render it right from PPro (not in the timeline but rather just rendering the clip. I can then import it into PPro and all is well...
Again, I know this isn't the same issue but if you haven't tried it already it's worth a shot.
Instead of playing this clip, try razoring that 8-th minute and ripple delete it. Then try playing the timeline again.
Why is Premiere handling the corruption so differently than the media players?
Because it is an editor, not a player.
Well, thanks for the ideas, but unfortunately neither suggestion did anything with the problem.
Can you elaborate on the difference between Premiere/After Effects reading of the audio versus the player's reading the file? Since the audio recovers immediately after the glitch when playing back the file (outside of editing applications!), I have to think that there must be some way I can recover the audio separately, but I don't know the best way to do this.

Are you able to produce a section of the file (perhaps a minute in length) which shows the problem? Where the start of the file plays OK then the problem section occurs. I'm not sure what tools would allow you to chop the file up at packet boundaries, but failing all else a hex editor such as HxD would be OK. It might then be possible to take a look at the packet structure to see if there's a obvious cause.
I hope this helps you help me! Thanks
Well that helps to see what you are seeing, but you would need to provide a section of the original MTS file to be able to see the original packet structures.
How can I go about doing that/what (parts of?) files would you need to see? I'm sorry - I don't have much experience yet with working with file-based video formats...I didn't think it would be possible to take a section of an MTS file directly, but if I can, I'll certainly do that.
Your original file is obviously way too big to provide for download.

It's not straighforward. There may be a utility somewhere that allows you to mark in and out points, and then cuts the original MTS file into exact copies of the marked sections - but I don't know of one offhand.
As I said earlier, you can use a hex editor to trim sections of the file before and after the section of interest, but finding the "section of interest" will be guesswork and may require a few attempts. Frankly it may not be worth the effort for you if you aren't familiar with using a hex editor.
I managed to get around the problem by converting the MTS to a mpeg, taking the audio from that and keeping the video from the original. I used Free HD Converter V2.0 after trying a few other conversion programs, unsuccessfuly. I'll probably remove the program, as it's a bit on the sketchy/adware side of things, but, it did do its job, so I can't complain too much.
Thanks for all the suggestions and help!
