External Enclosure and Dvd-r Problems

Hi, I have a Inspiron 600m running WinXp Home SP 1. I've been using a Pioneer A05 Dvd-R in my desktop for months without problem and wanted to use it with my notebook. I purchased a Bytecc (generic I believe) external enclosure, model # ME-320U2. Because the 600m has no firewire I purchased a enclosure that only supports usb2.0. The chipset on the enclosure is the Ali 5621 chipset. The enclosure has it's own power supply.

Anyway, I plugged it all in, set the drive to master, and connected it via usb2 to my notebook. It detected the drive fine and it shows up in the device manager as Pioneer DVR105 USB.

I am able to read DVDs fine (well I haven't actually watched a full movie but it detects and starts playing fine) and can rip dvds fine as well. The problem is that I cannot burn dvds or even cds.

I installed the Adaptec Aspi 4.71 updater and it seems able to burn CDs now but still fails when burning Dvds. Basically it begins the writing process but freezes during the lead-in. The disc has a visible ring that has been written on and is unusable after the failure.

I have tried different media, different programs, but nothing. I have also unplugged my other usb device (mouse) and attempted to burn but still failure.

I have no idea as to why it's not working! My assumption is that the Ali chipset does not support dvd-r drives but I can't confirm that anywhere and support on their and Bytecc's webpage is very weak.

I greatly appreciate any insight and help anybody can provide! I have logs of Nero's attempt at writing if anybody thinks that can be of use let me know and I can email those.

Thanks in advance for any help!
