To avoid what you observe (the disturbance of Winrad by some other tasks in the PC) try the following :

- In the Winrad screen, click on 'ShowOption', then on 'Show Status'
- In the small panel that will open, click on 'Lock'
- At this point push the Start button of Winrad, after choosing the DRM mode

Now things should be better,meaning that the fractional resampler has been disabled, and as a consequence the DreaM 
program works much better.
I don't know which decoder you are using, I suggest this    http://pdis.rnw.nl/norbert/inst_dream.exe
which will install DreaM 1.10.6
