Thanks for your info .
In 352x288 mode (pal-vcd) the results are excellant.The problem is that if i want to make SVCD i have no 480x576 mode for Svcd .......Only 704x576 (DVD quality).
Anyway even in 704x576 sometimes the quality is excellant,but sometimes when the movement is fast in the movie the quality sucks.Maybe in future a new capture driver solves the problem.
Anyway thanks again Betamax dude for your information
