I've been thinking about this for a while, myself.
I'm (obviously?) not qualified to code it, tho', and was a bit
disappointed to read the negative responses posted already. I guess
Mike's reasoning is sound, tho' - he certainly knows far more about
Myth than I do.
I prefer the idea of backend on-the-fly transcoding (BOT) to having
to keep multiple copies of the same program in storage. I'm the son
of a Scott and a Lancastrian, though, so maybe I'm just a skinflint
about storage space. ;)
If, as Mike observes, skipping/jumping/fast-forwarding/rewinding was
to be a problem then ideally my SD frontend would complain "woah!
your recorded this in HD... buffering..." whilst the backed starts to
transcode the HD original to SD size... the frontend would pause a
coupe of minutes then start - perhaps the SD version of the recording
could be treated like live TV?
BOT would additionally allow playback of video on devices with all
sorts of screen-sizes - mobile phones & hand-held gameboys, for
instance. I actually thought that BOT was a requirement for the
proposed flash-based player - it's been mentioned that that would
answer the requests for video playback on the Wii, but I'm not sure
if a flash video could fill the whole browser window on the Wii,
enough that an SD video could fit in it.
