While it isn't essential, it can be useful. However, it also runs without regard for anything else and is a pain to get it to stop or release resources when you are trying to do major work on your computer. I found it radically slowed the system and made it hard to install or upgrade other software because it hogged the CPU resources. It isn't dangerous in the sense that it does bad things maliciously, it is merely an uncontrolled and non-essential program.

It definitely slows typing response. Disable it as it affect Word, Outlook and Excel or any other typing required application.
I uninstalled MEdia Direct after my DELL XPS M1210 laptop became really slow, including typing delays in Outlook. PCMservice was eating most of the CPU resource: the issues went away right after uninstall.
It uses resources such that other programs don't respond.
Something appears to cause text to jump up and insert into paragraphs. Its an entirely infuriating problem on my Del Vostro. I useda program called Autoruns which can be downloaded from Microsoft which allows you to uncheck PCMService.- that helped the delayed typing problem but not the text-jumping. I'm entirely frustrated with Del ever having installede some wacky program that causes this. I'll never, ever, buy a Del again.
Glad i found this page. removed Media Direct and my typing has improved.
CyberLink PowerCinema (PCMService.exe) came with my Dell Inspiron 1420. Not really sure what it does. After a few years it started causing very noticeable and annoying keyboard delays. I disabled it and they went away. It feels good to be able to type fast again.
used in dell media direct also

Best practices for resolving PCMService issues

A clean and tidy computer is the key requirement for avoiding problems with PCMService. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic 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 6resmon 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 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
