Recommend Analog to HDMI converter?

We have an older PTZ camera that we'd like to use the video feed from on our Mini Pro. It has s-video and composite out, so I've purchased a converter. It looks fine when I plug it directly in to a monitor so I know it's working, but get no video when plugged in to the Mini. It can provide 1080p 60 output which the Mini should like,,, right? I've tried all the resolution settings on the converter and no luck, Tried all the inputs, no luck. If anyone has a recommendation, I'd appreciate it....Larry

One of the Decimator models maybe?

What converter are you using?
What format does the TV say the HDMI signal is?

I've now tried 2 different ones. The latest one had an on screen menu and when I plugged it in to a monitor it displayed both 720 and 1080p 60 with no problem. But when plugged in to Mini, nothing.

Thanks, I appreciate the suggestion.

Update: I was at Walmart and they had an analog to hdmi converter for $20, I thought what the heck, for that money I'll try it. And it worked. (?!!!). So the solution was just to keep trying converters till I found one that our Mini Pro liked.
