I have the most current version of Camtasia. Can I record video (and audio) from a TV via the HDMI cable connected to my Windows PC? I am making some instructional videos and would like to use some content from ads that appear on TV or some TV shows.
If you can get the video to appear on your monitor you can probably record it. If you're recording copyrighted content you are taking a risk because it's illegal in most cases. A video capture card will allow you capture some HDMI content directly to your computer screen. But a lot of that content is scrambled and un-recordable.
Another possibility is to "watch" the program via your web browser. You may be able to visit the broadcaster's site and watch the program via your computer, then record it as it plays. Or, search YouTube or visit iSpot.tv and play the commercials from there.
I have Comcast high speed internet; that service enables any content available via your subscription, including on-demand offerings, to be viewed in a browser on a PC, just like on a TV; the Comcast cable modem hooks to a PC via Ethernet or wireless
