DVD playback for some DVDs may be okay, but most will become jerky(drop frames) especially when the scene becomes "busy" e.g. whenthere's more action, pan-shots etc. If Task Manager is running, itshows that processor resources associated with the DVD player softwarerise (e.g. to >80%) during these "busy" times when frames aredropped. This can happen even with quite new, well specified PCs (e.g.2GHz Pentium 4, 256MB memory...). Common causeFrequently newer versions of Windows (WinXP,Win2000, etc) cause the internal DVD drive interface to revert to "PIOMode" (Programmed Input/Output - an old, slow, processor-intensive datatransfer protocol) rather than "DMA Mode" (Direct Memory Access -transfers data directly from drive to memory without much processorintervention). This completely throttles data transfer from the DVDdrive and causes dropped frames. A "bug" in Windows prevents thetransfer mode being set back to DMA either automatically (e.g. onreboot), or by even vaguely user-friendly intervention!This problem has been known about for over 2 years!
There is a hard-to-find Microsoft Knowledgebase article on it.
Open up Device Manager from the Windows Control Panel: (WinXP) -Start|Control Panel|Performance and Maintenance|See basic informationabout your computer, then select the Hardware tab, then press theDevice Manager button. Expand the "IDE ATA/ATAPI" entry. At this pointit helps to know whether your DVD drive is on the Primary or SecondaryIDE channel (typically you might find that your hard disk(s) are on thePrimary channel while your DVD and CD-ROM drives are on the Secondary).You can check by following the cables from the motherboard. Assumingfor now that the DVD is on the Secondary channel... double-click thatentry (or right-click and go to Properties). In the resulting dialogbox, click the Advanced Settings tab:

[ On my computer, Device0 (top) is the DVD and Device1 (bottom) is the CD-RW ]
If instead any of those boxes say "PIO mode" and you have a reasonably-modern PC then you've probably got problems!
Unfortunately owing to this Windows "bug", just setting thetransfer mode to "DMA if available" won't work, and won't "stick" onreboot.
SolutionMicrosoft's official solution can be found in their Knowledgebase article Q817472.In my case (and most I've read on the Web), the easiest solution is to"Uninstall" the affected IDE channel from the Device Manager window,then reboot, allowing Windows to re-install the drivers and sorteverything out from scratch!ideuninst.gif

Upgrading the graphics card would help, also there is a setting on the bio where you can increase the video ram usage

I have a problem w/ my Lite On SHW-160P6S DVD RW Dual Layer Burner which won't read any DVD or CD. Also, The door to the unit won't open unless you insert a pin in the little hole on the front of the unit...


You will have to open the unit. To be honest, it's a good idea to buy a new one as I had to change to belt and my drive started smoking when I turned my computer on.

Hi,

Thanks for coming to FixYa, The problem you have is either a well documented software problem or a failing drive.

Click the below link, then scroll down and click the "Fix It" button. Follow the onscreen instructions, restart when it's done and see if your drive re-appears. If it does, you're done, if it doesn't work then your drive is most likely failed and you should replace it.

Hope this helps FixYa,

Cd drive isn't working


I just had this happen to me as well. Try opening the case and re-seating all the connectors on the DVD drive and the mother board. If the drive still will not operate after that you may have to purchase a new one. They are fairly cheap and easy to install.

My Lite On DVDRW will not recognize any audio cd's...


Hi PhxROcker,

In these drives there are two lasers and two pick-up sensors. Normally in a combined head. One set is used for the DVD and the other is used for the CD. From you description it sounds like the optical sensor for the CD laser has expired! When you place a CD into the drive a small amount of information is read by the drive that identifies the disc type, manufacturer, it's status, capacity etc. If the drive cannot read this then it thinks nothing is present.

If you insert a disc does the LED on the front the the unit flash a few times while it spins the disc. Does it do this repeatedly? If it fails to read the disc does the LED stop blinking and the drive no longer spins the disc? If this is the case then your drive may indeed be faulty.

Sorry I could not be of any further assistance.

Regards,

Spare head 2.
