Underruns are bad.  

Try capturing the data to a ram disk instead of your hard drive if you
do not have a faster hard drive setup available (i.e. RAID).  I used the
ATSC demodulator a few months back and was never able to successfully
store that data down to my hard drive, so I allocated a 512 MB ramdisk
and used that which worked great.
