What? Cant hear the voices

It is not your age.....this is a common problem with HT in my experience. Much of what you are watching on a DVD was mastered for movie theatres....i.e. for vastly expensive systems with huge dynamic range.....which is obviously why the sound has more clarity on your Vr4 SR's. (a way better speaker than your TV speakers which probably compress/distort the bass and muddy the mid range clarity as the drivers go outside their linear response region at noormal movie SPL's).

BTW: Mid range compression at proper THX movie theatre levels is extremely common even in many higher quality speakers.

I suggest you just phantom the center channel sound through the Vr4 SR's and turn down the distorted TV sound altogether.

If you want a speaker with a particularly forward and crystal clear mid range then try to audition ATC. (This is not a plug for ATC ....they well are known for their mid range clarity)

Dynamic range is what adds clarity...and you need speakers that can handle what is on a DVD soundtrack.

More thoughts...

Some actors just plain talk to softly!

Example: "Stand and Deliver" starring Edward James Almos.

I love this guy ("Crocket, can I see you in my office?")
but he is what Seinfeld calls a "soft talker".

A solution to this can be found on some Denon receivers.
They have a feature that lets you program the volume control in adjustable increments.
I.E. Linear, +5 db, +10 db etc.

I "jockey" the volume all the time especially for action movies (up for dialog, down for explosions).

I found that distance-wise, the front L/R speakers need to be the same distance as the center from your litening/viewing position, otherwise, there are out of phase problems created as a result of the different distances of voice content speakers and this muddies the voice. I used a measuring tape and in my case, pushed the front L/R speakers back until they were the same distance as the center, which sits on top of my monitor.

Try it, it makes a huge improvement!

Again I reiterate...these sound tracks work in the movie cinema...the only reason they don't work in a home HT is due to poor quality speakers....believe me I have personal experience with both B&W and Bose systems that made voices very hard to distinguish (these were sub $2000 price range for entire set of speakers and clearly would not hold a candle to your Vr4's or a higher priced B&W such as the Nautilus)

Note that theatrical sound tracks are intended to be played back with a dialog level of 74dB SPL. On most Dolby Digital sound tracks, that allows for 101dB main channel peaks and 111dB LFE peaks. If you turn the volume down so the peaks aren't too loud, you'll have more problems hearing dialog.

The solution is dynamic compression. All Dolby Digital decoders are required to implement this (often called "Midnight Mode"), using meta-data defined adjustments to make the soft sounds (dialog) louder and loud sounds (explosions) softer.

All DVD players are required to include a Dolby Digital decoder - that's what runs the analog outputs. Their decoders should allow you to access BOTH compression settings: the standard one, and an even more severe adjustment inteded to avoid over-driving your TVs internal speakers. Look into it!

You may also have placement issues - if your main speakers are near (never mind in) large objects like an entertainment center or TV, you're going to have reflections that hurt clarity. Move them farther out - ideally 4+' out from the front wall.

Sitting closer to the speakers will help with the ratio of direct to reflected sound.

Finally, you probably have room acoustics issues. Dialog clarity suffers in overly reverberant spaces. Attractive fabric-covered panels are available to fix this.
