Computer help forum: DVD playback is slow / choppy

The new machine without proper motherboard drivers. Your note is void about details about these drivers, who installed the OS and what exactly was installed (drivers, drivers and drivers.)

Also there is that old XP DMA bug. Do flip the DMA to PIO as noted in the usual sites.

How many expert installs I run across with missing or outdated motherboard drivers.

Here's the XP DMA issue/note.

"The stuttering DVD drive"


Bob

For DVD and video issues, do you both have 1 GB of RAM.. It sure helps.. My home Compaq didn't do well at all with it's original 256 MB or RAM.. Adding more helped immensely.

Hope this helps.

Please explain.. AFter toggling the DMA settings, off, then on again for the "Primary IDE Channel", what does the "Current Transfer Mode" show in the "Advanced Settings" tab under "Device 0"?

Sorry where i go and check if the device is device 0 or otherwise?
I have three Primary IDE Channels listed on my IDE ATA/ATA{I Channels. All of them shows "Not Applicable"

I too have a new computer and the DVD drive is not working properly. It is a Gigabyte GA 965P S3 board, Core 2 Duo 6600 2.4, 2Gb RAM, Pioneer DVR 111, XP home SP 2, Albatron 7950GT, 2xSeagate 32-G SATA II attached to IDE RAID. I am currently confirming the motherboard drivers are OK. I have checked DMA which seems ok.

This is a very interesting thread for me. I also bought a new PC consisting of the following components:

- Intel DG965WH motherboard
- 2GB PC667 DDR2 memory
- 2 Seagate SATAII 250GB harddisks
- 1 Samsung DVD player
- 1 Samsung DVD writer
- Sparkle 7600GT videocard

Under XP my player is locked into PIO mode and unusable, however: the DVD writer is behaving correctly. Both are PATA drives btw.

I have tried everyhting I can think of:
- Switched the drives physically on the IDE cable
- Switched master/slave
- Different versions of firmware on the drives
- Newest firmware on my motherboard
- Only connect the player
- Registry hacking as mentioned at a link in another post here
- Installing every driver for the motherboard I could find
- Not installing every driver I could find
- Changing BIOS settings from SATA IDE to SATA AHCI to SATA RAID mode
- Several reinstalls of XP
- Etc. etc. etc.

Nothing, but absolutely nothing worked. There was however two instances where it DID work: The first one was after I installed Vista. Both DVD drives behaved as they should. But I cannot keep Vista, because I borrowed it just for testing this DVD problem. The second one was when I put an three year old DVD player as a replacement into the system. But I do not want to keep that one, because, well, it is old ...

I notice a few common denominators here with everyone having this problem: a Core2Duo processor, a nVidia videocard in the 7 series and SATA(II) harddisks. But I have no clue where to look beyond that.

It would make me very very very happy if anyone can come up with a solution for this, because it frustrates me a little that my shiny new PC shows this nagging problem.

Grats for solving the problem on your machine!

I already have the latest motherboard firmware, but I noticed Samsung released new firmware for my DVD player three days ago. No release notes for it, but hopefully it solves the problem on my PC as well ...

check the that you have the lates directX installed,
I think the late one 9.1


remenber those apps, always are hand by hand with audio or video realated files.

good luck

I rarely play DVDs on my computer but now that I am without another DVD player the situation has come up. The problem is I too am getting this choppy, slow, laggy playback from DVDs despite being able to burn and rip DVDs and CDs just fine from the same drive. The computer can also play video and music files (already on the computer) just perfectly, the issue only comes up when streaming from a disk be it CD or DVD. I have tried a number of suggestions including driver updates (nothing found), different playback programs (WMP 11 and Nero), uninstalling the secondary IDE drivers, and different dvd encoders. More recently I have tried the PIO thing that seems to be the common answer and I see one of my Secondary IDE's is on PIO only mode and I uninstalled it but when it came back online it went right back to PIO only. I did it a few more times with the same result. I tried changing the Transfer Mode to "DMA if available" but the Current Transfer Mode stays at PIO and is unchangeable. What could be my problem here? How can I fix my DVD playback?

Just tried the firmware update and it updated (LiteOn DVD-RW SHM 165H6S HS07 to HS0E) but, unfortunately, when it came back from restart the issue persists. I noticed my Secondary IDE was still in PIO so I uninstalled it but when it came back it went right back to PIO mode for both Transfer and Current Transfer and the issue is still very much a problem.
