Finished it. Crap pic, sorry, but my camera's a bit w@nk. Anyway, did do it double sided in the end, 4:3 on one side, and 1.85:1 on the other. Couple of tips for people who are going to do the same - MDF that fits in the hole may not do so when it's been painted. Surprisingly paint has a mass and makes the MDF bend and come out of the brackets. <img src="biggrin.gif" border="0"> Sorted it by bolting some aluminium bars to each side of the screen, frames the screen nicely with the top and bottom brackets too..

<br />Next upgrade will definately be a CRT projector, but i think i'll wait until i'm out of uni and earning money on a regular basis before i spend £4k. Then a decent sub. Oh, another tip, if you think you'll need 3 holes in the wall, drill 5, one will almost certainly go straight into cement and not brick and screw it up a treat.
