I'm reviving an old thread, so I'll quote a bunch of the message:

The vertical wavy lines showed up tonight and corrupted
four recordings across four different channels. I switched to
live tv mode and there they were... but, when I switched
the channel, they went away instantly!
So... what's the difference between my changing the
channel manually and the backend doing it to start a
recording? The only thing that occurs to me is the
on-screen display. But, I regularly watch recordings
via the same 350 and have OSD happening all over
the place... which doesn't 'cure the wavies'. Heck, I
was watching a recording tonight during an attack
of the wavies and didn't know it until after I finished
and saw that the evening's recordings were all junk.
Anyway, if this is purely an ivtv thing, I'll take it over
to that list. I was thinking that the difference between
'live tv channel switching' and 'backend channel switching'
could be a myth thing, so I figured I'd mention it here first.
