QAM and 8VSB are two different modulation schemes. 8VSB is used for digital off the air (ATSC) signals in the US. QAM is used on Cable systems. That's all about this topic but maybe it will help you sort out what you want to do. -Original Message- From: Michael Haan [mailto:[EMAIL PROTECTED] Sent: Monday, May 23, 2005 8:10 PM To: Discussion about mythtv; gentoo-user@lists.gentoo.org Subject: [gentoo-user] Tuning QAM w/ pcHDTV3000 I'm not sure I'm doing this right.
