MPEG is a video compression format devised by the Motion Picture Experts Group and comes in several flavours, but all use the same vasic principles. AVI is a video file wrapper format (Audio Video Interleave and can contain may different types of audio and video data, compressed using one of many different codecs (including uncompressed of course). All you need is the right decoder to play back.

The reason the avi's you have often seem smaller than the equivalent mpeg is that many avi's floating round the internet use compression based on one of the divx codecs. The divx codecs themselves are actually based on the mpeg-4 standard from the same people who brought you mpeg-1 and 2 (as used in (S)VCD and DVD) but in these files the compressed audio and video data streams are stored in the avi file wrapper rather than an mpeg stream. Tthis makes for greater portability and playback on most PC type platforms requires only a suitable codec.

Hope this helps

There is no difference as far as the name goes, an AVI is a MPEG 4, but a .mpeg could be an MPEG 1

Converting from AVI Mpeg 4 to Mpeg 1 is very simple using TMPGEnc, if you have a good quality source AVI, the then conversion will produce a good quality Mpeg 1

MPEG 4, has many codec's associated with it, DivX MPEG 4 being the most popular, it can produce very small AVI's of high quality. However Mpeg 1 does not compress the file as much, if sticking closely to the mpeg 1 VCD spec, It is normal for a DivX MPEG 4 to double in size when converted to a Mpeg 1 for use on a VCD
