If you have recorded 4 hours of program using the HQ mode (best quality) on the hard drive, can you use the high speed dubbing mode to record the program to a DVD+R at the EP mode (4 hours of lower quality) ?


The question that I want to find out is : does high speed dubbing requires the original signal quality to be identical to the recorded signal quality ?


Thanks !

Yes, for high-speed dub (HSD), the rec mode can't be changed. However, the real determining factor for HSD is total file size in MB... the total MB has to fit within a std DVD's 4424MB capacity, regardless of rec mode.


You can dub 4 hrs of HQ in real-time at EP mode, which will take 4 hours, or you can Divide the 4-hr HQ recording into 4 ea. 1-hr titles and dub each title to a DVD using HSD. The 3575/76 will fit 1:04:55 of HQ on a std DVD using HSD.

More detailed info on HSD here.

High-speed dubbing is a bit-for-bit dub, so nothing can be changed from the original to the dub. As Wajo says, the only way to do a HS dub is to break it into four separate titles, use four discs, same bit rate.
