Some DVcam(ex. Panasonic NV-DS1 DV camcorder) doesn't seems to set this bit even if it's for PAL. Fix the DSF bit for such cases so that we can send back the stream to the DVcam without problem. Problem Reported by: Richard Tobin <richard@cogsci.ed.ac.uk> - Make the number of bulkxfer packets(NPACKET_T) and the number of packets write at once(TNBUF) to be different values. I observe some block noise for large TNBUF. - Show the detection of NTSC or PAL. - Pad with 0xff rather than 0x00 for broken frames. - Bzero hdr[0]. - Remove unused code.
