Both. It's one of those hybrid things with a hard disk, plus it takes mini
DVDs.

When it comes off the camera it's got a VRO extension. Now how did I convert
that to mpg?

Can't remember - I did it a few weeks ago, and then got too busy to do any
more. It was probably the rather crappy software that came with the camera.
I'll have a better look at this tomorrow. (I'm in the UK and it's nearly
midnight.)

Yes, I've got VideoLan but I'd forgotten I had it. It does play the files,
but stretches them horizontally for some reason. They're already in wide
screen format, but VideoLan seems to make them even wider. Very strange.
Apart from that they play all right - the audio is fine too. When I try mpgs
from other sources that I've got saved on my hard drive, they play
perfectly, so maybe it's something to do with the wide screen format?

Yes, they play perfectly on that, and on Real Player.
I've just tried a file on WinAmp, and what happens there is that the
soundtrack works fine, but all I can see is the first image which stays
frozen.
QuickTime gives me an "Error -2048 Not a movie file"

I couldn't really ask you to go to the trouble of looking at one of my
files, could I?

OK, I've tried this. What happens is the opposite of the result in
VideoLan - the image is compressed horizontally, rather than stretched. Not
only this, but the audio becomes jerky. Saving it as an avi file works but
the resulting file is the same - horizontally squashed and jerky sound.
Could any of this be to do with the fact that it has been recorded in this
wide screen format? Maybe the software doesn't like it?

OK, you are now getting too technical for me!

If I've got time tomorrow I'll do some experimenting with the camera - I'll
try filming something in the 'normal' rather than wide-screen format, for a
start, and see if that works any better. And I'll try to remember how I got
the files off the camera on to my computer! I seem to remember having some
trouble with that as well.....
Thanks for all your advice so far. You've given me a lot of food for
thought.
