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.

I have the card installed, running 2.6.12-rc4. The drivers seem to load as does the firmware. I've built dvb-apps and tried: ./atscscan atsc/us-NTSC-center-frequencies-8VSB And got nothing but: >>> tune to: 803000000:8VSB WARNING: >>> tuning failed!!! >>> tune to: 803000000:8VSB (tuning failed) WARNING: >>> tuning failed!!! Does that mean there are no QAM channels I can get? Or do I need to do something more? What about 64 vs 256? -- gentoo-user@gentoo.org mailing list -- gentoo-user@gentoo.org mailing list
