All,

I'm going to try setting up MS Messenger to do video calls to my in-laws
across the pond. Presumably the webcam itself adds some CPU load to my PC
so are any particular webcams better than others in this respect?

Which cam you choose won't make any diffrence. What will though, is the
size/quality of the images you are sending. If I remember correctly MS
Messenger doesn't give you much choice as to size though...max is
320x240 I think.
If you don't already have the cam, I would suggest going to the shop and
having a look at various cams working so you can get the best quality
image as cams vary wildly in their quality. If you are sending/receiving
both video and audio, it is better if you are both on a broadband
connection also.

We will both have broadband. I hate to think what the quality would be like
over dial-up ;-).

As to possible load, I was really wondering whether there was the same sort
of issue as with ye olde "Windows modems" which were nasty Windows 95/98
modems that relied on the processor doing a lot of work, as opposed to
"real" modems which had dedicated hardware.

Someone has to convert the video into something suitable for transmission.
I wondered whether with USB modems there is a basic "grab the frame" from
the camera and then the processor has to convert into something for
transmission whereas with, say, a PCI card and camera, this might not be
pushed off to the card, sparing the processor from this arduous task.

I will go and take a look in the shops but frankly the UK shops are poor and
staffed by people who might, on a good day, be able to tell a Mac from a PC!

For best quality pictures, which you may not need for video conf, take a
look at the Philips Toucam pro 2 (840K) about £60 in PCWorld etc or for
smaller image stuff the cheaper creatives / logitechs should meet the
requirements at 320 x 240. Also give yahoo messenger a try against the MS.

Umm. The yahoo specs look tempting since they support both Macs (my in-laws
have Macs) and up to 30fps video, albeit a small picture.

They probably are, we promise not to send anymore, unless they are willing
;o)

Regards yahoo messenger we use it regularly in a group with NZ, Caribbean,
UK, Newfoundland. Tends to slow down a bit with more than one camera but
some users are on dial up. Used it from OZ on dial up when I was there and
we had 4 cameras on and it stayed stable for a good while.
