...What is The Differance between MPEG2 & MPEG 2-1...

I assume you are asking what the difference is between MPEG-1 and MPEG-2?

See http://graphics.tomshardware.com/video/19990924/video-3-03.html

...Why Do I get An Audio Video desync...

Your Pinnacle PCI card does not capture sound; that is handled by your PC's sound card. See Questions 20 and 21 of the Capture FAQ (http://forum.doom9.org/showthread.php?s=&threadid=32575), and see section 18 of the Capture Guide (http://www.doom9.org/index.html?/capture/start.html).

Thank U .. However I Was Asking About What Pinnacle Calls In It's Software MPEG 2-1 .. Strange .. I Haven't Heared About That Coz I Know MPEG1 & MPEG2 However The Quality Of That Format is lower then that of MPEG2 !

There is a developing Multimedia Framework standard, called MPEG-21. That I could find. But, I could find no information by google (or by searching www.pinnaclesys.com) for "MPEG 2-1". For clarification, I suggest you contact pinnacle; they have a technical support website as well as user forums in four languages.

If you're interested in MPEG-21, see http://www.chiariglione.org/mpeg/

It might be MPEG-1 video in an MPEG-2 system (for DVD compatibility).
