First of all, AVI and MPG are two very different formats.

Both are container formats, AVI can be pretty much everything.

AVI is a more compressed format.

Nonsense, see above.

It usually looks blurry and pixilated.

That's utter nonsense. Nowadays, AVI usually contains
MPEG-4 encoded video data which can offer far superior
quality than most MPG files will have. It's a question
of encoding quality anyway. MPEG-4 can look as good as
DVD video or better (if the original video source isn't a
DVD but something better of course).

MPG on the other hand typically looks much better.
|
Most MPG files contain MPEG-1 video data which usually
looks like tihs compared to something better like MPEG-2
or MPEG-4. A few MPG files contain MPEG-2 data which may
look better than a highly compressed MPEG-4 video but it'll
be much larger in size (4x or more).

This is because the frame rate of the video is almost double that of the AVI format.

WTF? The frame rate? Do you even know what that is? Maybe
you meant bitrate but that isn't true either. Videos typically use a frame rate of 24, 25 or 30 frames per second.
This has absolutely nothing to do with the format.

Therefore MPG files will always be much bigger than AVI files.

This is not true and even if they're bigger, this doesn't
mean they look better. MPEG-1 looks far worse than MPEG-4
at the same file size. For example, an acceptable MPEG-1 takes at least 10 MiB per minute, MPEG-4 looks fine at 6 MiB per minute and usually even much better along with a higher resolution.
