Media Player 12 (Windows 7) and Hoster 4.11 possible bug or issue

[ddouglass]

You kind of caught me off-guard with that one. I hadn't heard of WMP 12 and had to do some research.
What I found is 12 is only for Windows 7, Windows Mobile and Mac at this time.
One of the beta testers had reported a problem with a video he made without sound for an Instabutton use. After playing it Hoster had no audio out until he restarted it. I don't remember if it was on Windows 7 or not.
I would suggest you submit a Support Ticket so they can take a look at this.
Have you tried playing your intro video through Hoster to see if the same thing happens? Could be helpful if you do that before submitting the ticket. I don't know if they can come up with an immediate fix, but they can certainly look at it to see if they can fix it for the next or a future release.
