If you re-read the second part of my reply you'll see that I didn't have any problem with that setting.
I have a HV20 and I'll show you my wobbling... (I guess this is it) :)

1/50 that is, as I've got a PAL camera.
Sorry for double posting. Can't edit my posts for some reason.

I am glad I stumbled on this thread... I was about to buy an HV20 as I need a compact hd cam... I guess now I won't get it now... 
.
I understand that some of you think the wobble come from the cmos chip, which would make the most sense, but could it be coming from the tape mechanism or the head?
Here is my logic, please keep in mind that I have never actually held the camera, but from what I have read so far, the wobble doesn't happen if the camera is on a tripod, dolly, steadicam etc..., only when it's hand held. So I am wondering if somehow the pressure of one's hand directly on the camera affect so ever very slightly the tape mechanism , the head or the tape itself ? As I understand it, when hand holding the HV20, the hand is directly over the tape mechanism "door".
It might be a good idea to test the theory by putting the camera on a base plate and then shoot the camera by holding the base-plate, but without touching the body of the camera... Just and idea.

Wow... this thread is amazing. This wobble issue has been blown WAY out of proportion...I mean...95% of the time it is a non-issue. You have to be in some real extraordinary situations to get anywhere near the bad footage that has been going around. I speed down the highway with this cam mounted in my car...every weekend and no wobble issue..I do handheld (grant it I have to be more careful than with my old cam) and I get great footage...I don't even have a stabalizer...yet...
nur...I advise you to check out the plethora of videos available here and in other forums...most are shot with 24P 1/48 shutter...that is all I shoot in. Most of the cases where you find one shooting in a higher shutter speed is done in 60i and they are going for an effect...whether slow motion...or that staticky "Saving Private Ryan" look...other than that it is mostly 24P 1/48 shutter.....that is sort of the standard for shooting in 24P.
If you get the cam...just be careful with quick or jerky pans and any steady vibrations..LIKE A HELICOPTER..LOL. Even then...I think video can stil be shot in a helicopter...the original user did not know its llimitations when he shot that footage (I'm guessing)....it's all in the way its mounted...I have proved that over and over again every weekend when I shoot footage going down the highway...after some mentioned that it would be impossible.
Just remember...those same bumps..and jerkiness you did with a DV cam will look entirely different with this cam...but...in either cases...you would not use the footage anyways...:beer:

I agree 100%
Someone show me a better camera for the price.
Wobble issue do exist, due to the nature of CMOS sensor. But in most cases it is not a problem. It could become a big problem for anyone who needs to do pixel-accurate 3d matchmove but other than that, visually it shouldn't and is not distracting. At least that is the conclusion I got from madly shaking my unit.
Again, those wobble examples don't seem to be representative of what the problem is. I strongly suspect it comes from other hardware defect. (like malfunctioning OIS + rolling shutter or simply a rolling shutter that scans slower than it should)

In my test I had the camera screwed on a board which had a handle at each end and it wobbled like crazy, so I think that rules out your theory.I am glad I stumbled on this thread... I was about to buy an HV20 as I need a compact hd cam... I guess now I won't get it now...

Just wondering that you mentioned you use the HV20 with no stabalizer during handheld shots. Would you recommend using this feature or not for hand held shots? Does the quality suffer if you use the stabalizer. I am confident I can hold a good steady hand with this guy otherwise.

When I mentioned stabilizer I meant a Merlin or a steadicam etc. You seem like you might be referring to the Optical Image Stabilizer (OIS). Honestly…I have yet to use the OIS because I keep it off all of the time. I can’t comment on that yet but as far as hand held shots are concerned you do have to be very careful….even more than a DV cam. I think the combination of rolling shutter with 24p exaggerates the wobble but it’s very doable.

I wonder and have been thinking the same...
Emanuel its definitely a CMOS issue... but i like your idea

Thanks for bringing a moment of clarity as the signal is digital to tape.
But it is always good people are thinking.

I found the HV20 to be somewhat 'sketchy' when used for "action" shots.
Locked-down the HV20 camera is amazing, but otherwise .......................... :huh:. Perhaps in the hands of a very experienced camera operator this cam would work for action. ??? YMMV with this cam.
Looking for an HVX now. :beer: JohnG

The camera seems to shake with every sensitive movement your hand makes while holding. This seems to be only the case when you are zoomed in all the way to a subject far away. Not zoomed in, no shake at all, very steady. Possible fully maxed zoom shots will have to be stabilized.
Canon HV20
Cine Mode
HDV 24P mode
IMG off
With these settings:
Zoom to the max = shaky.
Zoom half way to normal, or no zoom = steady, no shake.
*Does leaving the IMG stabilization on effect the footage quality? It seems with the IMG on, zoom to the max, the "shaking" is gone.*

I walked past a big camera retailer last week and decided to try another one to see I could get it to happen. SO whilst the clerks were rushing around I gave it full zoom and a shake - nothing. Wonder if the cmos chips have been altered.
Those with the wobbling issue when did you buy your camera? Be interesting to compare.
