When your fiddling with the sync codes it changes where the decoder thinks the image starts. This happens to be inbetween YUV sequences. So if your changing the sync codes you also need to chagne the YUV order.
In usbvision.c, usbvision_set_input() you'll see that we set the YUV order with: usbvision_write_reg(usbvision, USBVISION_DVI_YUV, 0x06) Simply change the 0x06 value until you get the picture right. It can range between 0x00-0x07. Although the spec for the saa_7113 does give the order of the output because the sync changes where we start reading from its almost impossible to determine what this value should be, so just use trial and error. Thankfully there aren't many to try.
