What level of vLSO are you using?
I'd recommend NOT using ATC (auto throttle control) on the 'Bug. Its a known issue (doesn't hold 8.1 AoA) that they may or may NOT fix? So get used to using manual throttle on approach and keep the "E bracket" (HUD AoA) centered on the velocity vector by keeping the nose close to the 5 deg nose up on the Pitch Ladder. There's also an physical AoA indexer for that on the left bracket. I'd also advise working on lineup during your approach, as you start right of F/B (Final Bearing; ICLS needle left), let it "drift" over and then get left of F/B (ICLS needle right), then settle for left touchdown while aiming right. This doesnt help the approach at all and is evident when you land and almost tip over at trap.
Personally, I'd turn of ICLS when its not night/Case III. Its not like civilian cat-III ILS needles that can take you down to the runway. If you fly the needles, you'll always chase them and it wont get you on deck at the right wire. Once you get to the 3/4 mile, fly the ball ONLY.
Also, you are wayyyyy over weight. Look at the listings for "max trap weight" and I'm sure 14k will not even be close. On your FMD (Fuel Mgmt Display), its reading 14k, and thats why you make a pass at 155 kts. Thats far too fast. Not sure about the Super Bug but a CLEAN Legacy Hornet is 8.5k total fuel for MAX trap weight, w/145 kts approach speed.
The "dont settle" call means dont pull off anymore power cause you are going below glideslope. If you look carefully, you can see that you are starting to settle AR because thats what ATC on the Bug will do.

ExNusquam:
It works perfectly with my VRS. As for your videos:
1st Pass: You were low. That wasn't "On Glideslope". You were a solid ball or two below the "OK" region, and not correcting.
2nd Pass: You got a "Don't Settle" at the ramp because your sink rate was over 1000 fpm. The "Don't Settle" call is used if the AC is on GS, but the current sink rate will take the AC below it. vLSO shouldn't have given you a waveoff over the ramp, but, in real life, a sink rate of 1000 fpm anywhere on the pass would be a recipe for a waveoff or no grade, at best. It's highly unstable.
Also, as Sludge said, you are over max trap weight. Max trap weight for the SH is 44,000 lbs (You can find it on the CHK page), which should give you an onspeed KCAS of 137 kts.

As per the LSO NATOPS, a "Don't Settle" is a call for more power, as the current AC sink rate is going to take it below GS. "You're a little low" would be the next call if corrective action is not taken. Also, I'll have to fly an Auto approach, but I've never noticed anything odd about the VRS's ATC. You get crappy FSX ground effect instead of the burble, which is why it pulls power, but I've flown OK3 passes with ATC on.
micro:
Joeairplane and Sludge pretty much nailed it on the head from what I saw in those vids. Right for line-up and fly a "cresting" ball, not the needles.
P.S.: Joe, I like the sig! BKR!

Had my first Bolter today great work this mod is awesome.

600' - AR; 1500' - IC; 2300' - IM; 3100'-3600' - X; 4000' - BC; 5000' - BR
And instead of a solid lines for the start, use dashed lines. This would make the start variable, a window, as it should be for each pass.

Sludge,
Fair enough. However, my suggestion slightly differs: ;)
600' - AR; (1/4 nm) 1500' - IC; (1/2 nm) 3000' - IM; 4000 - X, BC; (3/4 nm) 4500' - BR
My guess is that the Start is where the pilot starts calling the ball, right? Given the approach speed of 145 kts, we'll have some 16 sec in the groove, and at 130 kts groove time will be exactly 18 sec... :)
And it's ok to add some randomization, or a window. But currently no dashed lines, sorry ;D

Since the cone has shrunk considerably by the time you get to the IC point, corrections for (LO) or (HI) are easily and safely done with small power adjustments...

Mike,
You can adjust the waveoff limits in the [Locus.GS] section of the vLSO.ini file:
[Locus.GS]
; The glideslope locus.
; This is a boundary which represents the locus of points in the vertical plane from which
; the aircraft will reach an on-glideslope condition at the ramp.
; Distances are measured in feet from the touchdown point.
;--- Dist Up Down
Pos.0 = 5200, 1.30, -1.60
Pos.1 = 2500, 0.75, -0.77
Pos.2 = 2200, 0.68, -0.72
Pos.3 = 2000, 0.66, -0.71
Pos.4 = 1600, 0.57, -0.60
Pos.5 = 600, 0.45, -0.55
Last two numbers are the glideslope deviations, up and down respectively. Generally, 'a little' area starts from 0.3 degree up to some 0.8 degree...
