Here are the scan settings I'm using:
Type: Full Scan
Frequency Table: Cable
Modulation: Cable (QAM-256)
Separator: None
Treatment: Minimal Updates (It'd be nice for me if there was a "create
duplicate")
It finds several channels, it just gives them all the same channel number
and therefore each channel overwrites the previous.
I've been following that wiki page over and over again. I find 215 possible
channels and trying to weed through them has been difficult. My TV only
finds 6 or 7 channels.
Running the mencoder script to automate that process gives me this error:
UNKNOWN TUNER TYPE
DVB CONFIGURATION IS EMPTY, exit
Failed to open dvb://1.
Cannot open file/device.
I'm running ubuntu 9.04 and this appears to be a well known issue but I
haven't found the solution.
Thanks,
Sherm
