Channels 266 and 267 have sound only on the tv with the HDPVR. The tv with the regular box works fine. How do I get picture with the HDPVR?
If I understand the situation right, you've only got sound on 266 and 267 but on your other cable box, you get sound and picture? If that's the case, then I'm guessing that your HD PVR most likely doesn't have MPEG-4 capability, as 266 and 267 (in most areas) are MPEG-4 channels. If you try to tune to them with a cable box which can't decode them, you'll get audio only. We've got more details on MPEG-4 here: Guide to MPEG4 Channels and Digital Cable Boxes
Hope this helps,
