Hi Graeme,
I have three essential questions for you:
- What version of MythTV are you using?
- Are you in PAL or NTSC country?
- Do you set some vbi-related options using ivtvctl before running MythTV?
I looked at MythTV 0.18.1 and I see NO setting for vbi_passthrough, so I fail
to see how MythTV can ever passthrough CC or WSS data.
Can you also make a test run for me that demonstrates the problem, preferably
after a fresh boot of your PC, and mail me the kernel messages (dmesg
output).
