It is a part of Creative MediaSource which monitors directories for media files. Probably hogs CPU & memory.
Media Sniffer for Creative MediaSource

As it says on the below link its a "Sound Sniffer", monitors the drive for new media files then automatically adds them to the media library.

Media Sniffer program from Creative. Came with my MP3 player. it constantly monitors folders designed by the user for new media files. does not hog resources as far as i know. overall, a trusted process that i allow to run in the background.
unnecessary process for creative mediasource, looks for files constantly which can be added manually and uses a ridiculous amount of cpu/memory
It is a part of Creative MediaSource

This program is ridiculous. It uses 50% of my cpu (I have an xps M1210 with core2 duo), quits working all the time, causes windows explorer to stop working. Might be compatability issue with vista
It is a part of Creative MediaSource which monitors directories for media files. Uses a lot of CPU & memory. If you have an old PC you should disable this process.
It's part of the sound drivers with Creative

Best practices for resolving MtdAcq issues

A clean and tidy computer is the key requirement for avoiding problems with MtdAcq. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the MtdAcq.exe process on your computer, the following programs have proven to be helpful: Security Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan.
