I ran a completely new jailbreak/restore of ATV2 to AppleTV2,1_4.3_8F455. I then ran through the installation instructions in the FAQ and installed the latest nightly - xbmc-20111024-c5758bf-master-atv2.deb. I also installed the update killer via ssh - apt-get install com.nito.updatebegone. I did not install any other software beyond XBMC. I re-uploaded my advancedsettings file to continue using the centralized MySql DB and thumbs db. I also turned off the "extract thumbnails" setting you mentioned previously in this thread.
I'm pleased to report that my files are no longer crashing to FrontRow immediately upon playing; however, they are crashing maybe 1-3 minutes in.
I tried 2 files - The Terminator and Tombstone:
Terminator (MediaInfo): http://pastebin.com/bvVrLNWV
Tombstone (MediaInfo): http://pastebin.com/9XrvDg9s

My CrashReporter stuff is *still* not showing up in private/var/mobile/library/logs/crashreporter; however, stuff is showing up in private/var/logs/CrashReporter, pasted below --- and I note that the filename, once again, says "LowMemory" -- I'm at a loss!
CrashReporter (LowMemory-2011-10-25-200851.plist, in above location): http://pastebin.com/YdGZNwbt
Thoughts on what I can try next? Am I ripping this files to be too large? (10 GB and 14 GB do not seem like a large 1080p MKV rip to me, but am I way out in left field with that assumption?)
Many thanks for your continued assistance!
EDIT: Something finally showed up in the mobile/library/logs/crashreporter, but this does not correspond to the logs above --however, it corresponds with the same issue -- mkv playback crashing to front row:
