Windows XP downgrades the Ultra DMA transfer mode after receiving more than The only optionįor the user who wants to enable DMA mode is to uninstall and reinstall the In this case, the user cannot turn on DMA for this device.
That six DMA transfer timeouts occur, Windows will turn off DMA and use only Windows XP will turn off DMA mode for a deviceĪfter encountering certain errors during data transfer operations. PIO mode is enabled by default in the following situations:įor repeated DMA errors. The trap is described in the following article (and also inĭMA Mode for ATA/ATAPI Devices in Windows XP Windows contains a trap in which quite a few computers seem to get caught Word and therefore causes a high and unwanted processor load. This requires many processor commands for each data Programmed Input-Output, where the central processor transfers data byte forīyte or word for word. The alternative, slow and inefficient data transfer mode is called PIO, Some newer, faster DMA modes are called UDMA (Ultra DMA). Procedure called cycle stealing, where the central processor memory accessĬycles are delayed for very short times to intersperse DMA controller memoryĪccess cycles. Processor, but by a small special processor called DMA controller. (Peter Frank reported successfulĪpplication on Windows 2000 with Service Pack 4.)ĭMA is an abbreviation for Direct Memory Access, an access method forĮxternal devices where the data transfer is not done by the central This article also applies to Windows 2000. Here is a more in depth writeup about the problem: Trying to find my media problem made my problem a longterm one!!! So, my stint of bad media, which had CRC errors at the end of the Memorex 8x disc, was hurting my DMA more and more each time I did a disc test. Thus causing failed burning on that drive untill the check-sum of errors is erased from the windows registry. This forced reversion to PIO will stay for ever and ever regardless of new better media being inserted. For burning, you will see "bursts" of CPU percentage being used. this means more CPU cycles, and more percentage. If things get really bad, it reduces to PIO (programable input/ouput), which is very slow and causes the CPU to handle the brunt of the tasks. However, as errors accumulate, windows will actively regulate DMA. An ideal transfer of data between your DVD-drive and your motherboard is had via a Dynamic Memory Access, which makes for less tasking on the CPU (performance percentage). When a CRC error comes across your IDE port (DVD drive), Windows will count how many errors it gets. For your stand along player, you get pauses/freezes/pixalation.

The systems I am talking about are all using the Intel Core i7 and ASUS motherboards for Core i7 - like the ASUS P6T and Windows 7 Pro 32 Bit and Windows 7 Pro 64 Bit.Bad media causes CRC (Cyclic Redundancy Codes) errors when read by any DVD-ROM player (stand along or PC). It happens with both HD and SD resolution EDIUS projects. If I try to mess with it before it finishes - it will say "EDIUS has become unresponsive" blah, blah, blah. If I leave it alone - it will eventually finish -but the render times are terribly long. It just stops "dead in its tracks" - and the "amount of time remaining" increases and the whole system appears to be unresponsive - can't cancel the render either. The problem I see - is the same on all systems - the MPEG-2 Exporter gets about 30% into the "render" and then becomes unresponsive. Now I am also seeing this same problem on other EDIUS systems that have 5.50 installed. I can export other formats like Quicktime and Canopus HQ AVI without any issues. I've been experiencing "Hangs" whenever I try to output MPEG-2 - using the Generic MPEG Exporter in both EDIUS versions 5 or 6. I am a long time EDIUS user (since Version 1.0) and intimately familiar with the entire line of boards and versions, third-party plugins, options, etc.
