DVD burner is reading and writing at 1/2 speed

I got a new 8x DVDRW daul burner about a month ago. I have since made over 20 DVD’s that worked fine. When ripping I was running about 4-5 M a second. Now all of the sudden using the same media, software, driver, and harware I can’t seem to get it over 2.5. When burning the actual write speed varies from 1-3-4-2-1-3-2-4-1-2-3. It’s all over the place. I am thinking it’s a hardware problem but would like more opinions. Thanxs in advance

Hi there and be welcome!

I’m taking a guess here, but I think that DMA isn’t enabled on your device. Check this thread for some info!
