Hi, all; I've been checking firmware 3.0.2, and I've noticed that the bug I mentioned earlier is still present - File Manager will freeze when browsing disks and finding certain video files. Eventually, the Android prompt about unresponsive apps will appear, but no amount of waiting will "unfreeze" the hanging File Manager.
I've checked the disks for errors, and they're fine; the files are playable, too (even in the older Himedia 900, in fact), not damaged - it just seems to be the File Manager in the newer firmwares. I'm about 90% sure it began with 3.0.1 (maybe 1 version earlier, but I'm pretty certain it was 3.0.1; I was browsing those files rather frequently).
Here is the Mediainfo log of the first file I reported - and in the second message, I'll paste the log of another such file I found. Maybe they have something in common e.g. in codec specifics, dimensions, etc. - either way, here is the first log:
