The files (that is, the video files that are left) are intact -- they can be 
played via MythTV. The problem is that MythTV is behaving increasingly 
erratically, as detailed in my earlier post.

I don't think it's a hardware problem. In my experience, most hardware 
problems show up either when accessing specific hardware devices or result in 
fairly random crashes. These crashes aren't associated with particular 
hardware and they aren't random; they occur when I try to perform certain 
tasks, such as play certain files (now deleted) or access MySQL via the Web 
interface. Other problems look like data corruption, probably in MySQL from 
my limited understanding of how MythTV stores data other than video 
recordings.

How does one import raw .nuv files into a new MythTV installation, if it comes 
to that? Can I just copy the files back to the data directory, or is there 
more to it than that?
