I'm confused about how things work (or don't work) on my MythTV system,
and I have a few questions. Sorry if I have some of the terminology
wrong - this is all new territory for me:
1. What does the wss option do? I can set it with ivtvctl, but when I
check the current setting it seems to not be set (see output below). Do
I even need it for standard 4:3 NTSC broadcasts?
# ivtvctl -b wss
ioctl IVTV_IOC_S_VBI_MODE ok
vbi service_set set to 00000008
# ivtvctl -B
ioctl IVTV_IOC_G_VBI_MODE ok
vbi service_set = 00000000
Is this a problem?
2. Is 'passthrough mode' only useful if I'm watching live TV and want to
use the TVs built-in CC decoder? If I'm watching a recording in MythTV,
does 'passthrough mode' even matter? Which decoder should I use for a
recording (TV or MythTV)? Or does that depend on whether I'm using the
PVR-350 decoder for video or the built-in MythTV drivers?
I can only get CC working with live TV using the TVs own decoder. With
recordings it's scrambled and unusable via the TVs decoder, and I never
get anything at all via MythTVs CC support..
I'm using ivtv 0.3.7 and MythTV 0.18.1-r2.
Thanks for any light anybody can shed on this.
Daniel
