This is kinda picky but as a professional it bugs me:
There are a number of lines (in the .rtf) which appear as for example:
<Can`t set trimmode parameter - AudioStreamNumber>
where the character which is supposed to be an apostorphe <'> (after the <Can> and before the <t> is actually a grave accent character <`>.
Some other lines have the character correct, such as:
<Can't reopen video window. Playing stopped.>
Most lines do not end with punctuation (the most recently quoted does and the line quoted earlier does not). There should be a decision as to whether all lines should or should not be punctuated at the end (Lines that are questions must finish with a Question mark <?> Personally I like punctuation but in dialog boxes, etc. it is often superfluous.
Is <trimm list> a misspelling? I would expect <trim list>.
<config> should be spelt out <configure>, naturally when it is part of the running text and not when it is part of acommand name or the like (if there is enough room in the dialog)
