I have a MKV video file. Can you please tell me how I can find out the video/audio codec of that file, and how I can find out if it is 1080p or 1080i?

I have a Windows 7 desktop PC.

Thank you.

You could always install VLC Media Player. It plays almost every format. Hit Ctrl+J while something's playing and it will show you the Codec info.

You can use MediaInfo to find every possible info about the given media file.
(There is a GUI, and a CLI version too.)

GSpot became obsolete; MediaInfo is fine. +1. – Mehper C. Palavuzlar May 4 '11 at 6:49
