There is no relationship between the notation such as 8x recording support and the recordable time.
The recordable time of a recordable DVD is determined by the transfer rate. Switching the recording mode of the DVD recorder can be changed by setting the DVD recorder. Generally, you can record 120 minutes on a 4.7GB DVD in standard (SP) mode. The notation such as 8x recording support is the dubbing speed from the hard disk to the DVD, not the recordable time.
