Ipad 1 upgraded to iOS 5, "play where left off" video function no longer works, and codecs aren't recognized.

Question

for some reason after updating to iOS 5, my videos no longer play where i left off, even if i set on the settings to do so. and yes i've tried restoring again, playing video over and over. resetting the video over and over. after a while of tinkering i figured there might be something wrong with the iOS.. also the codecs say "unknown" now, weird. anyone else having these types of problems?

Answer 1

@bokehftw no problem.
Update:
I did my best to compare the two files i have in question.  One pulled directly from my itunes library, and the other from my storage location (exact same file used to import INTO my library).
Now I admit that analyzing metadata is NOT something I claim to know how to do, but I am capable of googling some stuff and trying to figure something out. 
So, unless I am missing something here, unfortunately, my findings point AWAY from the metadata thing.  It seems that most of the metadata was actually stripped out of the iTunes file.
iTunes File:
Original File:
Only thing I blacked out is the name of the file in question - you will just have to trust me that it's the same exact file (except the original was used to "import" into my library and the iTunes file is literally pulled from my iTunes Media folder).  Someone who is more familiar with the framework of iTunes may be able to decipher a little better - and for all I know, iTunes uses a funky way of adding it's own metadata that can't be read by third party programs (like Media Info - which is what I used).
Ah well, back to square one.   If anything, I hope this gets others with more experience/knowledge involved on the subject.
And on a final note (related to the initial problem) I've also noticed that since iOS5, editing my "info" tabs on my media files (read "movie" files - not music) directly on my idevice, I've noticed it's hit or miss if it actually sticks.  Prior to 5, I had no problems adding info (such as Artist, album, etc.) and having it show up that way.  Now, the filename itself changes, but the additional information is now no longer shown.  wierd.
