I use the same transmitter and have the same problems. I have several devices and the only thing common was the dib7000p. After a week of trying to debug to no avail. There appears to be no way to back the gain off from the tuner. It is the 2K/8K and/or power mix. The windows driver also suffers the same problem but it attempts a number of retries to gain lock. An all 8K transmitter in the South West(Beacon Hill) is fine, so full switch over should be fine. -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
