I've never used one of those Linksys devices, but thats very odd
(and a pretty bad product!) if it couldn't keep up with writing only a
single HD stream. There must be some way to improve the performance.
As a last resort, it should be possible to write to one of your
faster Myth HDDs and have a cronjob move the files once the recording
is complete to your NAS and symlink it back to the Myth directory.
