My VIA EN12000 does both with not too much trouble.
It has 1GB of RAM and 1.2 GHz C7 single core CPU. It records 3 SD
channels from 1 DVB-T multiplex 24/7. It's not blazingly fast but does
the job.
The only issue is a memory consumption phenomenon: VSZ and RSS (virtual
size and resident set size) grow continuously. Below are the numbers in
reverse order, latest on top. As you can see VSZ has more than doubled.
For RSS it's even worse:
