My old Samsung external SE-204N finally gave up on me and I went out and got a LG GE24LU20 external. I am running it on a Windows XP machine. On my old set up I was using Convertxtodvd to convert and burn video. Burn times were just a few short minutes on the Samsung. Now, right out the gate, burn times are literally hours and hours for one disc. I use Verbatim media. I have tried 4x, 8x and 16x just to see if things changed, nothing did. I have checked that all channels are set to DMA. I am not at all tech savvy so I am here to get any and all suggestions from those who are. Thanks in advance.
