OK, i tried to change everything in tmpgenc settings to 16:9 NTSC but the test file is not exactly 16:9

I opened up the vob files in PowerDVD and its fine but when tmpgenc converts despite I set it to 16:9 source, it is slightly bent upward.

How can i change it? DVD2SVCD does it fine but I dont know how to do it in tmpgenc

thanks
