Upping the bitrate gives diminishing returns after a certain point, see:


There are other parameters besides bitrate, in addition to resolution
there are a slew of parameters that can be set on the PVR's encoder, but
remember that the PVR is a consumer-quality inexpensive device.

But having said that, a PVR can yield very good results. If I look
carefully I can see the artifacts produced by the card, but most
viewers, not knowing what to look for, do not see a difference between
the direct source and a Myth-reproduced picture.
