Myth does its actual recordings by basically dumping the stream to disk.
The only way therefore to record at a lower res would be to choose a
lower res channel. Some stations will have an SD and HD channel
showing the same content. This would be good if this is to be the only
front end.

Another option would be to transcode your recordings as a user job
to a lower resolution. This would also be more disk-space efficient.
I use mythnuv2mkv[0][1] for this task but there are other options available.
