Ripping and burning times

I have been using DVDFab and it has been working very quickly and very well until recently. It was ripping at about 5-5.5 MB/s and was burning around 4x. All of a sudden it just started ripping between 1-2 MB/sand ripping about 2x. Any ideas of what could’ve caused this or how to remedy it? Thanks

Make sure the drives running in DMA mode 2 or 4.
