Q: converting avi to quick time

AVI is a Microsoft container. If the file was encoded in an iPad compatible format, it can be viewed with QuickTime.

There are 3rd party apps that provide for this such as OPlayer.

You can use third-party players unless the videos are Full HD. The following players have excellent MSMPEG4 / DivX / XviD (the most common codecs used in AVI files) support:

You may also want to convert them into MOV / MP4 etc. files so that the stock Videos can also play them back. Then, you will want to use Handbrake. Do NOT listen to people recommending other, commercial converters - they're, in most cases, inferior! (See for example my related benchmarks and posts at https://discussions.apple.com/thread/3861279?start=15&tstart=0 , on the second page )
