Newbie Analog Svideo Help!

[Freakish]

Hi Peoples, I've just found GBPVR to my surprise works with both the analog and digital portions of my Hybrid tuner. I really want a program that can record from my TV Tuners S-Video input, and this one looks great.... But......
I cannot seem to find a way to select Composite/SVideo pins and inputs/outputs or view their inputs?

Is there a way to preview the SVideo or Composite Inputs?]
I can preview the analog TV channels using the Tuner assistant, so i know they do work, but how do i preview or see S-Video or Composite?
It seems if i do not have an analog channel set in config, Live TV just sits there doing nothing, when clicked....And if i have both Digital and Analog, how do i switch from Digital to analog, while in the "Live TV" area?

Thanks for any help on the matter...

You may find it only partially works. Devices without an analog hardware MPEG2 encoder will only be able to live preview, not recordings.

The app automatically chooses the video input based on the capture source settings for that channels. For example, if you create a capture source for the svideo input of that device, and it has one channel associated with it, each time you view that channel it'll switch to that input.
