I've tested this with version 1.0.5 (5135) and 1.0.3 (5132). Neither works.
Last month I was able to record video with the s-video connection.
Last weekend, I upgraded my Mac from Lion to Mavericks.
I have not changed my cables, connections or VCR/DVD combo drive for source video.
I am no longer able to see video in the Easy software via the s-video connection. I see "No Signal" in the video window of the Easy software. However, I am able to see signal via the composite video connection.
When I test one video connection, I disconnect the other so there is no video interference.
I would like to continue to use s-video.
