I don't use DVB.. but I presume it works like all other capture cards

The signal is being captures, compressed, saved and then displayed.. and 
the result of the compression is what you are seeing.

Try increasing the quality in the "recording profiles" part of setup and 
see how that works for you -easier to test your settings under the "live 
tv" profile - then when you are happy copy the settings to the other 
profile you use for recording
