Yes and no. It depends on how big N is, and what size you're
wanting to transcode to. If you want to be miserly on HD space and
efficient on resolution, transcoding is a good thing. The PVR-[23]50 does
a poor job at low resolutions and bitrates. I actually record things I
want to keep (READ: record to DVD) at higher resolution and bitrate than
necessary (640x480, 4500/6500kbps). When I get ready to archive to DVD, I
denoise, 2-pass VBR transcode down to 352x480 at 2200kbps. Results are great
(It's cable SDTV, so anything above 440x480 is overkill). I would
probably use 480x480 if it were a DVD standard size, but 704x480 is too
space hungry to be worth it.
Again... this is for *archiving* shows if you want the best
quality/bitrate. For the convenience of time-shifting, live with the
20-50% space overhead on the HD.
