When I ran out of 8x DVDs I bought some DVDs up to 16x speed. They didn't work on my 5 year old Sony DVR. I think I could dig up my DVR manual, change some settings and maybe fix it (or maybe not), but I didn't want to switch between settings. Until my dash cam fails I will continue to use the 8X. It worked great!
