don't burn with an 8G D9. Because it takes a long time to burn, and it's not very good to support D9 in car equipment now. This thing is double-layered. It's not easy to read. It's best to burn it with a professional such as NERO or ONES. I never burn it with WIN7. It's insecure. It's enough to burn D5 in car DVD, so as not to have too many bald heads.

If you support FLAC, you can install FLAC. If you support MP3. There's not much skill in getting on MP3. Just burn the NERO Buring data type directly. Just burn it at the slowest speed. However, it should be noted that the on-board equipment also has the problem of picking the disc. If it can't burn it again, try another brand of disc.

PS: Most on-board vehicles don't support D9, that is, the 8G (actually 7.8G) disc. It's very difficult to read.
