most profiles marked as requiring hard subtitles?

Hi, I just want to check if I understand this correctly:
Do the lines

  Code:

                <Subtitles>
                        <SoftSubs mime-type="text/srt" />
                        <HardSubs>
                                <RequiredFor container="*" />
                        </HardSubs>
                </Subtitles>


in the generid DLNA profile mark all files served to Sony Bravia as requiring hard subtitles (if they are accompanied by a subtitle file)? And hence the "Enable burn-in subtitles" choices of "Always" and "Only when required" will lead to the same result?
Would I be allowed to tweak the RequiredFor line to something like

  Code:

 
<RequiredFor container="avi" vCodec="msmpeg4" vFourCC="div3" />


?
Thanks in advance.

Yes, your understanding is correct.

You can tweak a profile by adding a "RequiredFor" statement as you are suggesting (almost) however:

• It should preferably be done against a device profile, not against the Generic Profile; and
• the RequiredFor statement only works to the container level (not vCodec or vFourCC) - so you can only add it as <RequiredFor container="avi">
