help, shuddering video playback

ok I first noticed it after I would be running on battery that the video would shudder and the sound would be choppy. it would do this even after I pluged the power supply back in and I had to reboot to get rid of the problem. but this morning I was trying to watch a video and it still would shudder even after I rebooted. I don't have an idea whats going on. I am using nero showtime and have no problem using it on my desktop, which is less of a PC than this 1705.

 

Is your DVD that's copied pirated in it's orginal form? Because that can make all the difference. Also, having your adapter plugged out cuts down a lot of performance power.

 

no I am using store bought DVD's, and it even shudders after I plug the PSU in.

 

Most likely your cd/dvd drive is set to PIO mode instead of DMA mode. To correct this go to the device manager (right click on my computer-->properties-->hardware tab-->device manager)-->double click IDE ATA/ATAPI controllers to expand it-->right click on secondary IDE channel and select properties-->advanced settings tab-->make sure device 0 is set to DMA on transfer mode.

 

ok I tried that. my only 2 choices are PIO and DMA is available, and current mode is PIO. it won't let me change it to DMA

 

i have the same problem plz help!!

 

okay, you'll probably have to uninstall the secondary device. Go back to the device manager, and right click on the secondary device. Then select Uninstall. Reboot and hopefully it should detect it and change it to DMA mode.

 

so i dont screw this up, uninstall the secondary ide channel?

 

note: when i first had this problem i used sys restore to bring it back to the original state, and the sound worked fine, but a couple days later it screwed up again

 

Yes, uninstall the secondary IDE and then reboot. Even if it is set to DMA if available, it sounds like it is still in PIO mode. So in order to recycle it, you have to reload the device. If you uninstall the secondary and reboot, XP will detect it and update it. It should be set to DMA when it reboots, but if it doesn't, then it should allow you to change it at least.

If you don't feel comfortable with that, you can remove & reinstall your cd/dvd drive. XP should detect it as new hardware and hopefully update the driver - assuming that you have the phillips drive.

Now, if you have NEC, Sony, TSST or anything else, check out support.dell.com under the drivers section. There should be a driver for your cd/dvd drive under the removable storage area.

I know the secondary method with fix the choppy issue, but I'm not sure about updating the drivers.

 

i solved this prob with my nero showtime by 1.updatin nero.2 in showtime setting >video quality> choose lowest setting 3. in video mode settings (nero) choose no deinterlacing. hope this helps.

you cant tell any differnce quality wise either

ps i still have same prob with playback on all my other media players though(media center, real, windows media)

 

then its the PIO DMA issue southern girl was talking about. My friend's e1705 came from dell the same way, and i followed those instructions to fix it.

 

You can change some of the software, but that is only going to change it for that particular software. If you want the drive itself to be changed, you have to get it to change to DMA mode. With the new dual cores, this has been a common problem and the common answer. If you really need further evidence, do a search on Choppy DVD playback in our dell forum - you'll come up with several threads, and usually in the end the answer is to change it to DMA mode.

 

ok I did what ya said and now it says ultra DMA mode 2. so I guess it worked. I'll try a movie some time this weekend and see if it works correctly. thanks for your help

 

try another software to play it. such as VLC @ videolan.org

This is a new problem i never heard of .
