If it is recorded in HD, the resolution should be higher than 512x288. That sounds like a SD broadcast on an HD channel.
I also don't know of any hardware that "records" HD in avi format.
What is the source and type of the files in question and what are you trying to do with them?Google is your Friend -
Typical broadcast HD is either 1280x720 progressive or 1920x1080 interlace.

Resizing won't get it back its original resolution either--it'll be an upsized, blurrier ESTIMATE.

Well you see i downloaded the video for "backup purposes" the quality is amazing and looks hd and it is said to be shot in hd only but the problem is the resolution, also if uncompressing cannot do it then couldnt a program like transition hd or tmpgenc 4.0 solve the problem by increasing the resolution, i hear those programs can do it without losing any picture quality

Take a 1280x720 HD still frame. Reduce the frame size to 1x1 pixel. Now enlarge that small image back up to 1280x720. What will it look like? Will it look as good as the 1280x720 original?
Or let's try it this way: I have two numbers. I'm going use my advanced number resolution reduction process to reduce them to one number. The result is 97. What were the original two numbers? -

And from your description, you are downloading files that were recorded in HD and then reduced in resolution. This is done to make them compatible and follow the "standard" for video releases. Unless you are using an HTPC, you wouldn't be able to play them back in HD resolution anyway.

He has a low resolution video that may once have been high resolution.
