I don't think mythweb is inserting the bad data in the database.

To me, this seems to be a bug in two places:
 1) EIT (I assume that's where the program info is coming from) -- it
    probably should sanitize things before it puts them in the database    
 2) Mythweb - should be more robust against questionable data in the
    database

I don't use either so I can't really recommend a good fix or test one.

You should be able to create an account to raise a bug.

Using grep, it seems to me the issue you are hitting is in 
mythweb/modules/stream/stream_asx.pl in mythweb (because in the other
cases, there is whitespace around the - between title and subtitle). 

You might be able to hack it to sanitize the suggested filename a bit in
that file -- you might need to adjust the other scripts too though.

Something like this may work: (completely untested)

# Print out the HTML headers and the ASX file itself
## *add this*
$title =~ s/\W/_/g;
$subtitle =~ s/\W/_/g;
## *end add this*
print header(-type                => 'video/x-ms-asf',
                -Content_length      => length($file),
                -Content_disposition => " attachment; filename=\"$title-$subtitle.asx\"",
                ),
            $file;
