No, not at all.

I presume you are connecting the audio output from your digibox to the 
audio input on the PVR USB2 device...

What I am suggesting now is that you connect some OTHER device's audio 
output (e.g. a CD player) to the audio input on the PVR USB2 device and 
evaluate the sound quality again.  If the sound quality is decent then 
you've just proven everything on the PVR USB2 side is fine with respect 
to audio on the composite input and there must be some kind of problem 
involving the connection of the digibox.  If the sound quality still 
rots then you've ruled out any aspect of the digibox as being a factor 
in this and we have to look inside at the PVR USB2 side.

But if you've got good audio when using the antenna then nearly 
everything on the PVR USB2 is already OK.  The only different between 
antenna and composite input is a software audio routing configuration in 
the PVR USB2 device hardware itself - everything downstream of that 
point is identical in the two cases.
