A Myth frontend will always look for the video in its RecordFilePrefix,
even if it was recorded by another backend. Therefore, you could
transcode (keeping both old and new), then move the transcoded video
(the standard-def one) to a recordings directory that's mounted on all
your standard-def frontends and move the original video (the high-def
one) to have the pre-transcoding name (I think that would just mean
removing ".old" from the filename). The filename must be identical in
both the HDTV and SDTV directories.
However, this gets far more complex if you have combined
frontend/backends with HDTV capture cards and standard-def-only playback
because you only get one recording directory per host. So, your HDTV
cards would be recording to the SDTV directory and you'd have to
transcode, then move the high-def recording for those...
And, when you factor in the hours it will take to transcode each video,
you might be better off--as long as you're not severely lacking in
CPU--paying the $20-$40 for a 5200 for each frontend...
Best of luck with whichever approach you choose.
