You're right in a technical sense of
course - I meant "improved" over the one-time-use transcode for
watching / deleting when overseas.
I use different settings for recoding the ts files for keeping -
x264 runs slower and at lower CRF, audio at higher bitrates. I
chose my words carefully "retaining 100% perceived quality". *I*
really can't tell the difference, having spent a fair bit of time
with my nose against the screen looking for MPEG artifacts,
blockiness, jaggies etc - it's taken a little time to tune.
Others can of course choose their own settings.
In a couple of instances though I'll still argue that perceived,
if not actual technical, quality is improved: grainy films +
where for example the BBC has telecine'd older material at
ambitious resolutions and transmitted at equivalently ambitious
bitrates, and programmes where the broadcaster forgot that modern
screens no longer overscan and left a line or 2 of signalling at
the top, as attached. There's an option to crop this during
conversion.

Yup, I see your reasoning behind it. Only one thing though...
Transcoding is not going to give you improved quality regarding of
what encoder and settings you use. Size can be reduced which is a plus
but there's degradation with every trip a stream makes through an
encoder. Encoding always has and always will be a one-way street in
terms of quality.
