Batchfile for killing DriveSpeed

[Spragleknas]

I am having a rather strange problem.
Like everyone else, I do not want my DVD to spin @ 18x.

Problem is:
- The internal drive speed setting does not work (unresponsive DVD playback)
- With Nero DriveSpeed started: same result as above

Solution:
- Starting Nero Drivespeed
- Killing Drivespeed process
- Playback is OK.


So I have choosen to startup DriveSpeed wit windows, and made this batch file:

PING 1.1.1.1 -n 1 -w 5000 >NUL
taskkill /f /im DriveS*.exe
taskkill /f /im DriveSpeed.exe

Line 1 is giving NeroDrivespeed 5 sec. to start before it terminates it.
2. line is to avoid it to be started as "Drives~1.exe" or simular.

Question is, can I use wildcard (*) like this?
Are there batter ways to terminate this process (PID value is never the same, I believe)
