(i already done the search i cannot find a good book or DVD to learn detail about this)
This site has a lot of good info on this topic. You may want to read up in the DVX user forums as well as purchase some recommended reading posted throughout the Internet sites including this one. The best possible way to learn is to rent the equipment or offer your time as a cable person / utility to established mixers and learn from them. Best of luck.
This book : http://www.trewaudio.com/store/product.php?productid=1120&cat=149&page=1 is a very valuable source of real world information. No bullshit here :)
I second Matt. Can't stress enough the value in being able to shadow someone experienced. While I was lucky enough to study sound in film school, I'd say 80% (if not more) or my knowledge was acquired by getting out there and working - which, needless to say, frequently means working utility for little to no money while you learn the ropes. If you know of anyone in the field, give them a shout - mixers are frequently looking for a cable person and are usually more than willing to show you the ins and outs when time allows on location. Time spent on set with a working professional is invaluable; you'll learn more on a couple shoots with a friendly pro than you ever could with books/dvds alone. Put in the hours and you'll get there. Cheers!
