Ok, it turns out I don't need to muck with mythtv, it happens within a few minutes of a md5sum *.mpg running. (This is lucky, because its a hassle to get the fglrx driver working with the new kernel - just trying compiling the quantal version on precise now)
So here it is with the upstream kernel, and this time a useful oops :-) For linux- image-3.5.0-030500rc5-generic_3.5.0-030500rc5.201206302035_i386.deb The behaviour of still being able to mount again no longer works.
