Hans, Apologies, I think the preempt-enabled kernel I built was screwing with the driver. The results I'm now seeing using a stock FC3 kernel are identical with and without the patch, ie. at the beginning of a wide-signal capture, my TV will flip to wide mode. This also works while switching between wide and narrow channels in Myth. If it's a wide signal - I get 16:9, if not, I get 4:3. However, skipping around a wide recording immediately loses the wide mode and I'm unable to get it back again within that particular recording.
It's like the wss signal is only embedded at the start of a recording or when a wide-mode change occurs in the signal. During a skip-forward, Myth (or my TV) reverts back to 4:3 and permanently 'forgets' that the stream was wide rather than defaulting to the previous VBI mode. If this is indeed the way VBI wss works, perhaps MythTV should be caching the most recent wss mode and using that as the default until it's overriden by another mode-switch..? Cheers, Wilf.
