Andy, all,

thanks very much for the replies. Sorry it's taken me a while to respond.

Yes, I did try that, but it didn't help.

Ok, I will try those as next steps.

Good to know, thank you. By the way, you might be surprised to know
that when my old PVR-350 burned up about a year ago, Hauppauge sent me
a brand new one as a replacement at no cost. Very generous of them.

Please don't bother on my account. At this point with Composite out
working, I'm not willing to put much time into troubleshooting it
myself :)

Thanks again, I appreciate your detailed reply.
