I'm having a problem with 1Click DVD Copy 5, and their tech support refuses to help me, or refund me. I downloaded the free trial, made the 3 copies, it was fantastic. I paid for the money, got the registration code, and it failed 17 times in a row, with many different DVDs, not just the same disc over and over. A couple of the times it didn't even get to the burning process, it failed just on reading the disc. 1 time it burnt 13% of the way and then ejected the disc. 14 times it burnt 1% of the way and ejected the disc. The only advice they gave me were to do a complete reinstall (which did no good), and also to check my DMA settings. They told me to change the settings from PIO ONLY to DMA IF AVAILABLE. My computer was in DMA IF AVAILABLE, but it was locked into PIO ONLY MODE anyhow. I don't know what any of this means, I'm not a techie type guy, so it's all over my head. Anyhow, after I told them that the computer was stuck in PIO ONLY MODE, they told me the problem was with Microsoft and not them, and they refused to offer more support. I asked for a refund, they declined, despite the fact that the review site that I found their company on said they have a 30 day money back guarantee. According to microsoft at http://www.microsoft.com/whdc/device/storage/ide-dma.mspx: "For repeated DMA errors. Windows XP will turn off DMA mode for a device after encountering certain errors during data transfer operations. If more that six DMA transfer timeouts occur, Windows will turn off DMA and use only PIO mode on that device. In this case, the user cannot turn on DMA for this device. The only option for the user who wants to enable DMA mode is to uninstall and reinstall the device." They way I read that is that their software did something that killed off DMA mode, and they are responsible for why I can't get into DMA MODE, whatever that i. So, my question is this: Can anyone help me to either get my computer into DMA MODE, or come up with some other solution to help me get the software to work? I'm at my wit's end, and so frustrated right now. Please help.
