E-System laptop with slow dvd playback

My laptop has been playing dvds perfectly well since I bought it 3 months ago, but now when I watch them in full screen they playback is 'choppy'. The audio and visual are out of sync and the content is slow.
Any suggestions on how to fix this would really be appreciated.

    this is great. quick question though; my CPU is changing constantly, so the second highest thing keeps changing.

    And when I end the process, will I be able to start it again easily?

    Thanks for being so helpful!

    OK the high processes are dwm.exe and SynTPEnh.exe , and obviously the task manager itself. Nearly all of the other processes are staying at 00, and it's just the four at the top that keep moving around.

This can be a bit of a tricky one to figure out. My initial response would be that you have another program or process that is causing your computer to play 'choppy' video. When you have a newer computer that was recently working just fine and now all of the sudden the video is choppy, it is usually due to another process using CPU cycles that are so important to video playback.

Start playing a DVD, but don't go to full-screen mode. Open the Task Manager. Right-Click on the task bar and select Task Manager. Click on the 'Processes' tab. There is a column labeled CPU, click on the heading 'CPU' twice. This will order the processes in order from highest CPU usage to lowest. The top two processes will most likely be your DVD player and the process that is causing your choppy playback.If the offending process isn't essential (i.e. anti-virus), then click on said process and then click the "End Process" button.

Hope this helps.

    To be honest, how easy it is to restart the process depends on what it is. If it is something like iexplore.exe (Internet Explorer) that is the problem, it will restart the next time you start the program. If it is a more obscure process, it will restart when you restart the associated program.

    If you'd like you can post or send me the processes that are high on the list and I can help decipher what programs they're associated with.

    Hope this helps.

    These are two processes that you can disable, but you may notice changes in how your system responds.

    First, the SynTPEnh.exe file is related to the Synaptics Touchpad on your notebook. Disabling this process will not disable your trackpad, but it may disable some of the extra features of the trackpad (i.e. scrolling).

    Second, the dwm.exe process is linked to the Desktop Window Manager. This is the service that makes all of your windows look pretty. It can be a bit tricky to disable, but I think it might be worth it for you to do when you are viewing DVDs.

    Here is a link to a page that describes the dwm.exe process and also tells you in detail how to disable it:

    Hope this helps.

write the publishers - they're using more complex methods of preventing people from legally watching their legally purchased DVDs on anything other than sanctioned standalone players.

No dvd playback

try downloading a fresh copy of whatever it was that you used to view dvd's such as POWER DVD or whatever the encoder was that you used to use. If you used Microsoft Windows to watch DVD's it's possible the drivers are corrupted, try installing a copy of power dvd and then also a copy of fddshow.exe

I encoutered that problem 3 months ago, the DVD ROM recognized only few DVD disc, other DVD's won't even the windows is freshly installed. The laptop was return back to the store they replace it.

If all of those are not working maybe its time for you to enjoy the warranty of your laptop if the laptop has a warranty. hope this help.

Problem Playind DVDS

Even the most basic pc should be able to play DVD's, firstly try a different dvd player sofware, see if any change and don't have any programmes running in the background. If you still have the same problen, i would return to your retailer and ask for a exchange, because some companies do not like you messing with the hardware or settings, and of course can void your warranty.
