Need to Modify SDK Videoplayer to Allow Display of Image

@ Mark:

Thank you for your input. However, I wish I was able to figure out how to implement your suggestion. Sadly, my experience with this type of code is very limited so far, but I'm happy that I am learning a lot as I push through these challenges.

@ Joel:

I thought I tried to implement the few changes you suggested. Unfortunately, I'm still getting the same results I reported last night.

Here's the section of code as it stands now:

'***************************************************************
'** The show detail screen (springboard) is where the user sees
'** the details for a show and is allowed to select a show to
'** begin playback.  This is the main event loop for that screen
'** and where we spend our time waiting until the user presses a
'** button and then we decide how best to handle the event.
'***************************************************************
Function showDetailScreen(screen As Object, showList As Object, showIndex as Integer) As Integer

    if validateParam(screen, "roSpringboardScreen", "showDetailScreen") = false return -1
    if validateParam(showList, "roArray", "showDetailScreen") = false return -1

    refreshShowDetail(screen, showList, showIndex)

    'remote key id's for left/right navigation
    remoteKeyLeft  = 4
    remoteKeyRight = 5
 
    while true
        msg = wait(0, screen.GetMessagePort())

        if type(msg) = "roSpringboardScreenEvent" then
            if msg.isScreenClosed()
                print "Screen closed"
                exit while
            else if msg.isRemoteKeyPressed() 
                print "Remote key pressed"
                if msg.GetIndex() = remoteKeyLeft then
                        showIndex = getPrevShow(showList, showIndex)
                        if showIndex <> -1
                            refreshShowDetail(screen, showList, showIndex)
                        end if
                else if msg.GetIndex() = remoteKeyRight
                    showIndex = getNextShow(showList, showIndex)
                        if showIndex <> -1
                           refreshShowDetail(screen, showList, showIndex)
                        end if
                endif
            else if msg.isButtonPressed() 
                print "ButtonPressed"
                print "ButtonPressed"
                if msg.GetIndex() = 1
                    PlayStart = RegRead(showList[showIndex].ContentId)
                    if PlayStart <> invalid then
                        showList[showIndex].PlayStart = PlayStart.ToInt()
                    endif
                    if Showlist[showIndex].contentType="image" then
                    showImage(showList[showIndex])
               else
                    showVideoScreen(showList[showIndex])
               end if
                    refreshShowDetail(screen,showList,showIndex)
                endif
                if msg.GetIndex() = 2
                    showList[showIndex].PlayStart = 0
					if showList[showIndex].contentType="image" then
                    showImage(showList[showIndex])
               else
                    showVideoScreen(showList[showIndex])
               end if
                    refreshShowDetail(screen,showList,showIndex)
                endif
                if msg.GetIndex() = 3
                endif
                print "Button pressed: "; msg.GetIndex(); " " msg.GetData()
            end if
        else
            print "Unexpected message class: "; type(msg)
        end if
    end while

    return showIndex

End Function

And here is the XML file:

</feed>

As you suggested, I took out <streamFormat> and just left <contentType>.

Then, I shortened:

if Showlist[ShowIndex].streamformat=".gif" or Showlist[Showindex].contentType="image" then

To this:

if Showlist[Showindex].contentType="image" then

But, still, it's just not opening the image. It still does the "retrieve" for a split second and then back.

Any help is greatly appreciated. And, if this type of function is just not meant to coexist within a video app, then that's fine too. This channel will be video driven. This is just an extra "perk" that I'd like to have in there.
Thanks again for any advice that could assist me in accomplishing this.
