Problem with Flash video/dropdowns in Mozilla

Question

Am trying to add a flash video to a webpage using a
Dreamweaver extension called Active Slideshow Pro by DMXZone.
The page can be viewed: www.faith.org.uk/Testindex.html
In IE7 it works fine. The video shows and the dropdowns of
the menu work correctly.
In Mozilla Firefox the video works but the dropdowns do not
show.
If I remove the block of coding which is generated by the
DMXZone extension:
<object
classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000" codebase="
http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=7,0,0,0"
width="514" height="129" id="testshow" align="middle">
<param name="FlashVars"
value="xmlFile=testshow.xml&preloaderBackColor=0x0099FF&preloaderBorderColor=0xCCCCCC"
/>
<param name="movie" value="slideshowpro.swf" />
<param name="quality" value="best" />
<param name="scale" value="noscale" />
<param name="wmode" value="transparent" />
<param name="bgcolor" value="#000000" />
<embed src="slideshowpro.swf" id="testshow"
wmode="transparent" quality="best"
flashvars="xmlFile=testshow.xml&preloaderBackColor=0x0099FF&preloaderBorderColor=0xCCCCCC "
scale="noscale" bgcolor="#000000"
type="application/x-shockwave-flash" width="514" height="129"
pluginspage="
http://www.macromedia.com/go/getflashplayer"
/>
</object>
The page works in both browsers and the menu dropdowns appear
correctly.
I would be most grateful for anyone's advice on this.

A discussion with Adobe support lends the idea that MPEG
layer 4 might be an issue. That since these videos come from DVD
perhaps encoded with MPEG layer 4 that that could be the reason tha
all of them have this problem. (Some were done using AVI - I have
to check and see if that makes a difference)
BUT
According to the PDF from Adobe Design - Flash Video Encoder
Wizard - By Tom Green and Jordan L. Chilcott
Flash should be able to convert an MPEG4 file. (Well it does
but they all stop after 30 sec.) Now how do I solve this problem?
All the videos still stop after 30 sec.s

Flash Video Encoder Wizard
By Tom Green and Jordan L. Chilcott
The first thing you have to understand about the use of video
in Flash® is the original
video must be converted to a format Flash can read. This
format is FLV (Flash Video)
and you can either use Flash, the Flash Video Encoder, or
third-party software to
create the FLV file. If you use video-editing software such
as Adobe® After Effects®,
you can also export the file as a FLV file. If you are a
Dreamweaver® user, the current
version of Dreamweaver—Dreamweaver 8—contains a
feature that allows you to add
an FLV at the click of a button.
The purpose of the Encoder, therefore, is to convert the
video file to the FLV format.
When you installed Flash Professional 8, the Flash Video
Encoder application was
also installed on your machine. If you also have QuickTime,
Adobe After Effects,
Avid Studio, or Final Cut Pro installed on your machine,
they, too, were given the
capability to use the Encoder when it was installed.
If you will be converting a video to the FLV format, the
video must be in one of
these formats:
• AVI—Audio Video Interleave
• MOV—QuickTime 4 or later
• MPEG—Motion Picture Experts Group
