hey guys... i am new to the site. i got a new computer for christmas and it came with a dvd burner... i was pretty stoked to be able to use it to back up alot of my audio and video files. it can burn up to 16x, but lately i have been getting extremely low burn speeds. it used to take me less than 2 minutes to make an mp3 cd, now it requires 15 minutes... i havent tried to burn a dvd again yet. i cant imagine how long that would take. i also noticed that when i play videos off of dvds which i insert into the drive, they play choppily... this had also never happened before.. can anyone here help me? i dont know if this is faulty, something misplaced or loose internally, or something i can fix with settings... any and all help will be greatly appreciated.. thanks alot
SLOW RIPS,Could be in PIO mode, READ HERE
Go to
My Computer
Control Panel
System
Hardware
Device Manager
IDE ATA/ATAPI controllers
Open the installed IDE channels (Primary and Secondary)
Click on Advanced settings
You will see the transfer mode. Change it to DMA if available. If any are PIO or stepdown dma you need to un-install the channel (right click on the channel and choose uninstall) and re-boot. Windows will reinstall the device and return it to DMA mode.
Be careful when using this procedure because if you have an older hard drive or storage device that does not support DMA you could corrupt your data.
After the Windows IDE/ATAPI Port driver (Atapi.sys) receives a cumulative total of six time-out or cyclical redundancy check (CRC) errors, the driver reduces the communications speed (the transfer mode) from the highest Direct Memory Access (DMA) mode to lower DMA modes in steps. If the driver continues to receive time-out or CRC errors, the driver eventually reduces the transfer mode to the slowest mode (PIO mode)..

What is DMA mode?
DMA (Direct memory access) mode is a high performance mode for transferring data to and from devices, in particular, to CD and DVD burner devices.
The burner devices can function in either DMA or PIO modes. DMA mode allows the processor to transfer large pieces of data with very little software overhead - therefore requiring low CPU utilization. In this mode, high speed burning can be performed in background with other programs running.
PIO mode requires CPU processing for every few bytes sent to the device, so that CPU utilization becomes very high when trying to burn at high speeds.
