I have an app which displays up to 12 short (~ 6 second) mp4 videos sequentially, however despite seemingly overcoming the problem as reported in this thread, again I'm having some of the videos randomly not showing. The watchdog timer (Timer5) I implemented ensures the display continues to the next video, but I'd like to fix this "random" problem so all videos show.
Here's an extract of the code which includes the relevant subs:
As can be seen, I repeatedly use Mediaview1 and issue a
command prior to initializing MediaView1 ready to display the next video. The error which occurs causing a random video in the sequence not to show is captured by
and this is an example:
but the media is valid because most times all videos display in sequence.
I wonder whether
is sufficient to truly dispose of all resources ready for the initialization again and so perhaps Mediaview1 is not completely ready to be initialized or perhaps memory is not completely cleared leading to these random errors. Although I'm yet to find a video file size that never throws an error, it does seem reducing the size of the video files is beneficial, eg. 2mb files appear to error less than 5mb files.
Because it's random, I'm finding it hard to systematically diagnose the cause and so any ideas ideas/suggestions would be warmly received.
Here's an extract of the code which includes the relevant subs:

If IntroVideos(mediaFile & ".mp4", arrayHome(a, 1).SubString2(0, 2).Trim) = True Then
