No need. The PVR-350 encodes the video straight to MPEG-2 in hardware, 
so the only thing that your CPU has to do is essentially a file transfer 
from the card's memory to disk. File storage is rather low-overhead, so 
very little CPU use.

The .nuv file is actually an MPEG-2 file, but MythTV still saves it at a 
.nuv file, so no conversion is required, even if you want to burn to DVD 
or (S)VCD. You can even watch the files in Windows; just tell Windows 
that .nuv files should be opened by your viewer of choice, and you 
shouldn't have a problem. The viewer will usually be able to tell that 
it's an MPEG data stream regardless of the extension.
