Slightly off topic, but I have just found out that Argos are selling a DVD player, that will play AVI and DIVX etc (I just had to buy it at £50). This is great as recorded movies, or similar, can be played straight from a disc - no need to render, just plonk the AVI file straight onto the disc and hey presto. AVI is good because it is highly compressed and if you get a decent enough size, you will get good quality.
