I found the same problem. You can not record any stream with windows xp SP3. It works great with SP2 and lame XP, but not SP3. The problem is not just NCH Software, the problem is across the board with all other recording software. I have downloaded and tried many trial versions. At first I thought it must be my computer setup, but after trying all of the other trials on an XP not SP3 computer, they all worked. So, the problem is definately SP3. NCH, do you have a solution or fix? Otherwise, your software is worthless to us.
