Still in preliminary assessment here, but I so far noticed skips using the 
following within $HOME/.bash_profile

tty2) screen -wipe; ionice -c 2 -n 0 screen -RD 


I commented/removed this line and am using the defaults and am now hearing 
skips and no breaks.

... still trouble shooting here.


(On a somewhat seperate issue, spent 4+ hours last night trying to install 
wintv-6 or wintv-7 to compare it's performance, and am finding wintv-7 does not 
recognize any of my (hvr-1950 & pvr usb2 29xx) devices.  What joy.  I could 
elaborate on the number of multiple reboots, blue screen and other errors but 
will politely save you the misery.)
