Thank You Tie, for the hope and the link! I will!
:
| Wow.. I am impressed of your analysis... I didnt take the time to search
it
| in such depth...
|
| I suggest you repost all this info to a specialized newsgrou for
| multimedia...
|
| its this one in case you have not seen it:
|
| microsoft.public.windows.vista.music_pictures_video
|
| This is a general newsgroup, but perhaps in that specialized one you might
| fall onto a MVP
| or even someone from MSFT.
|
| Good luck in finding the best solution.
