I tried the latest 0.4.0 on my Pi. Conencted to 1A power supply 8GB Class10 SD card and direct to LAN.
As described that equipment sounds fine, but all PSUs are not equal, and some never live up to their spec's.
I would definitely try using another power supply before ruling that out as a possible cause.
Please view this video. There is not sound, sorry. My cam microphone is broken.

About that test video, I'm a bit surprised that you only launched stuff from the 'On Deck' shelf, instead of entering the proper library section lists. It's not quite the same thing, though both methods work fine for me. But I assume you've tried both too, with similar results as for the shown failures.
I have one of the very first Model B Rev 1.0 Pi's.
I never heard of any problems with early versions of that model.
Mine is probably newer, but as long as the design is unchanged that should make no difference.
When it starts its got the rainbow but everything loads as normal. I thought the rainbow meant somekind of issues? Can anybody clarify.
The 'rainbow square' is quite normal for a hard powerup or a hard reboot.
It might not be seen for a 'soft' reboot though, when the firmware just restarts itself without full boot sequence.
Basically when I try and play a video it just grinds to a halt, flashes black and comes back to the main GUI.
Noted.
Even photos do not show, just black screen. Also I can press right and left on photos and I can see the Pi is laoding somethings, or press backspace and it goes back to the main GUI. But then the text goes all garbled, and wierd GUI artefacts.
The artifacts I saw seemed mostly to consist of text lines superimposed on top of each other. In the plot description it looked as if it was trying to add more text without proper scrolling.
What is the problem? ANybody got similar problems?
At this point it's hard to say what's wrong, but two things I'd suspect first is either a bad flashing or a bad power supply.
I'd try re-flashing the SDcard, and if possible also try another PSU (preferably a 2A unit).
Insufficient power can cause just about any odd behaviour, as some of the digital logic will become erratic with incorrect voltage.
