Web plugin not always working in IE

[countzorg]

First of all, I don't like IE but we are using it here. Also would like to say sorry if this has already been addressed. I had a look around but didn't see exactly what I was after (famous last words!!!)

The web plugin is really good, although I have just found out I am using the older way of doing it.
THe plugin works well in Chrome - almost always fully functional.
In IE it doesn't always display the video (overlay?) but plays the sound of a stream. I am essentially using streams that we are creating via a couple of MOI+ boxes that run TVheadend. They work directly in VLC)
If I refresh the page a few times, the video will then show video. It is quite random (Chrome seems to manage it full time)
I have included an example of the code I use (a section from the website). I would like to have the option of turning on subtitles (from live feeds and TS(mp4 too)) but I guess that will be a different dig/thread.
We do have VLC installed on the machines. I do have the last cab file linked in, although I assume this is over-ruled if you have a localised version of VLC installed!
The stream address in here is just one I found as an example.

Thanks in advance for any pointers/advice.
Thank you for taking time out to even look.
