Optio RZ10 Video recording problem

I've just bought the RZ10 and am working through the features.

I've a problem recording video.

The video and sound appear to record ok but when I play them back, either through the camera or on my PC parts of the recording are missing.

eg

I recite the alphabet a to z but when I paly it back I get
a b c d g h i l m n p
etc

about every couple of seconds I loose a second

Can't find anything in the manual about this but suspect it's user error

Anyone else had this problem - or like to point out my incompetance

Are playing back from the camera and downloading to the PC and playing back the file EXACTLY the same?

As far as I am aware yes.

I thought to begin with it was the fact that when playing back on the camera there is a 'shuffle' time set in the 'Slideshow' option. Hence I put the memory card in my PC and used Windows Media player to play the file directly.

Excatly the same result - every few seconds it jumps a few seconds in the recording.

I have an RZ10. I haven't used the video feature much, but I can't say I have noticed this problem when I have. You aren't accidentally hitting the shutter release while videoing are you?
The camera is in France now so I can't test it for you.

Hi Gwyn

Don't think its me hitting the shutter release as it happens at regular intervals and on every video shot - but I'll have another go later and keep my shutter finger under control !

It sounds like it may be faulty then. Try it again later and if it still does it I would take it back.

What about when you use the sound only option? And as a voice memo, so no video just sound?

Before you take it back, what sort of memory card is in it?

Haven't tried just voice memo - I'll try that later

I've tried various SD cards (256Mb, 512Mb and 2Gb) all of which worked perfectly ok with my previous Pentax camera - not sure of the make and model though - I'll check when I get home tonight

Have you formatted the cards in your new camera?

Yes all the cards have been formatted in the new camera (the 2Gb one took a while!)

Mine has a 512Mb card in it, and doesn't give any problem so I don't think the card is the problem. Though I did format mine in camera before using it.

I was wondering about the 'Class' of the cards?

Mine is so old I don't think it has a class .

Ken, Not sure about the class - Ill check tonight; are there any that might cause a problem?

Ken and everyone

Firstly many thanks for all your comments and suggestions this afternoon - you've made a newbie feel very welcome.

Most of the cards are quite old and do not have a class on them.

My most recent card is a 4Gb class 6 card.

I put that in and it reported "Memory Card Error" (I've had that with most cards when I put them in).

Took it out, put it in again and it was ok
Reformatted it
Recorded a video

No problems - played back fine on the camera.

That leaves me with a couple of concerns though.
Why do I frequently get "Memory card error" when I put one in?
Why do I need a class 6 card to record video - the spec for the camera doean't list any minimum requirements for cards?

Any thoughts?
