With regards to collaboration with your institute , sure it'd be a great chance to open such discussion, i'll contact with you later to see what we could do each other. Aabhas, Thanks for the Link , i'll contact with you later also to try again sending/receiving the dvts stream Sang Woo, I think now we have found the roots of the problem , in fact my camcorder only support PAL, thanks for the clarification. Chris , it seems that our only solution at the moment will be Gnu/Linux , we have no other choice. Regards Muhammad
