D-VHS could also hold Dolby Digital & DTS 5.1 audio. As far as I’m aware, D-VHS never got to the point of having PCM 5.1, although that may’ve been on JVC’s drafting board, just like incorporating 1080p was on the drafting board. The JVC HM-DH5U had HDMI, so PCM 5.1 would’ve been possible in future models.Only VHS digital audio machine really was that Technics. If you had an early generation VHS recorder (pre HQ) you could use one with a Sony PCM-F1 processor. But that system worked better with Beta or U-Matic due to more stable tracking. That said, D-VHS did have PCM audio but uncommon due to being late in the era of videotape.
