Many DVD's have DTS 5.1 sound, which is massively better than Hifi VHS which was stereo only (similar to Nicam stereo audio on PAL analogue services), pretty well all the others have ac3 5.1 audio.
HiFi VCR and NICAM stereo are both VERY high quality, DTS5.1 has more channels that's all, it's certainly not 'massively' better - and apart from the extra channels probably not noticeably better at all.
But as you also said - don't play your CD's through your TV

Nicam 14 bit 32kHz sampling, CD 16 bit 44.1kHz, ac3 stereo 16 bit 48kHz, DTS 24 bit 96kHz
DTS-HD much higher.
Not that you would hear any difference on a TV, you certainly can on a good HiFi. DTS has a immediately obvious increased dynamic range.

What is the rationale of 48kHz and 96kHz? On the face of it taking CD at 44.1 and dividing by 2 (for Nyquist) and taking a bit off is still plenty even for youngsters. For most of us even 32kHz is probably enough.
The higher sampling frequencies would seem to be specmanship like the amplifiers that used to go up to 100kHz.

48kHz was an alternative sample rate on early digital kit such as DAT machines, probably because it's a nice round number unlike 44.1 and engineers seem to like multiples of 16 as well for some reason
Part of the idea behind using higher sample rates is not to get a frequency response into the ultra sonic but to reduce the artefacts of the anti-aliasing filters required.
If you are not careful with the design a steep slope filter, as used in digital converters, can have audible effects below the cut off frequency. By using a high sample rate you can move those side effects out of the audible range.
Do you have difficulty with English. Compared to the difference between a good 1080p50 HD camcorder and a VHS camcorder yes the difference is tiny. I acknowledged the difference in my post (which you ignored)
As the HD camcorder can create better picture quality than you can get from any broadcast source, then in the situation you posted
it has precisely zero advantage in a home situation..
Aha! Now I get you! I had to skim-read your earlier post as I had a train to catch.

Indeed, when compared to stereo sound on Freeview, listening to NICAM through a pair of decent headphones was like a breath of fresh air struck my headphones. Unfortunately, as this was listening to the dying days of analogue in the Tyne Tees region (Bilsdale mast), I now lament that we are stuck with sound that can handle more channels, but seemingly a more obviously compressed dynamic range.
When something sounds bassy in MPEG2 or 5.1, it just sounds bassy. When in NICAM it sounds *convincing* and bassy. Same for sounds like "sparkle" and such.
Anyone who listens to DVD's or Hifi VHS sound on a TV has to not give a monkeys about sound quality. especially with a modern flat screen they sound terrible. Who in their right mind would listen to CD's through a TV ?
Maybe those two little phono plugs, on the back of the VCR / DVD player, were hooked up to an auxiliary channel on their HiFi or surround system?
Never forget VHS, or more precisely video recording technology, was a massive leap forward when machines became more affordable and reliable at the end of the seventies and remained the principal way to watch recorded television and pre recorded entertainment for 25 years..

You'd struggle to hear the difference on a good HiFi, and certainly would tell any difference from CD - you don't need 24 bit or 96KHz sampling

Or so one theory goes anyway.
