Videostudio can't trial

[apwood]

I have added the following topic to MediaStudio Pro forum:

As you can see, I'm trialling MediaStudio, but probably will buy VideoStudio - can't trial VideoStudio because I'd have to pay first to get AC3 (Dolby Digital Plugin).

Is there a way I can ensure AC3 audio will work (and hopefully not have problems referred to in the link above), without having to pay for it first?

Can I be sure if it all works in MediaStudio, it will still work when I buy VideoStudio?

Any advice in answer to the queries on my post in the MediaStudio forum would be appreciated.
