We had the ability to do so in the past. The problem with it is that 
some characters cannot be used in some locale settings and/or with some 
file systems and some file systems have different 
requirements/limitations for file name length and ...  Therefore, the 
user changes a file name and it seems to work now, then later something 
on the system changes (locale settings, file system, ...) and then the 
file gets a broken name and "MythTV is broken".  Or the user changes the 
file name in the shell/script/... that's running in one locale and "it 
works" but has MythTV running in another locale and it can't find the 
file so "MythTV is broken."

We decided to support only the built-in file name structure for 
recordings since it uses only characters that are supported in all 
locales and on all (known, reasonable-for-use-with-MythTV) file 
systems.  Ideally, rather than trying to encode information about the 
recording into a file name/extension (a la Win 3.x/DOS), we would 
support writing of the information into in-file video metadata.
