if you have interest in documentaries...
and I live near MQ uni... we can get together..
I prefered to borrow and make a copy of iso in the harddisk..
I found in that case I can keep a flawless media... otherwise I always found trouble with the DVD I bought long time ago and cannnot be played...
if you have interest, pls email me: zhmz888@gmail.com
hopefully you are not live too far away...
