Re: PAL-I tuner defaults to PAL-BG

[Andrew Wilkinson <andrewjwilkinson@xxxxxxxxx>]

Yeah, I'd come across your post with that in and it works, but I'm
actually trying to use this with mythtv. MythTv appears to reset the
tv norm to PAL-BG whenever it records so I get no sound :-(

I've only just started digging into this and I think V4L1 only let you
say I want PAL while V4L2 lets you say I want PAL-I, so this actually
an application rather than driver issue, though if anyone was going to
tell me I was wrong this is the list where it would happen!
