Not true. There's no need to re-encode the PVR-250 output with the settings we
are talking about. The whole point of this thread is what settings he wants
to use so as to _avoid_ needing to re-encode, and I simply confirmed his
request for a sanity check.
There's nothing about using Linux rather than some other platform that
requires you to re-encode video that is already DVD compliant. :) Likewise,
the particular type of DVD writeable disc has no bearing on the video stream
spec.

I'm not aware of anything in that thread that concludes that re-encoding would
be necessary. It's mostly us discussing the particulars of how to author a
DVD containing compliant captured video. :)
