Trying not to be too nit picky, but it's composite.  Component capture
isn't possible on a PVR-150.  Composite is a lower quality option than

You must run the cable from the STB into the SVideo on your PVR150, as
well as Audio from your STB in the form of 2 Red/White RCA cables.
Then in your mythtv-setup screen under Capture Cards, you will need to
setup your PVR-150.  Once that's done, you need to define Input
Connections, specifically, the SVideo connection to your STB.  The
rest should be well documented on the wiki.

It sounds like you are trying the wrong video device when trying to
directly view video.  Check the output of dmesg after you modprobe
ivtv to verify which video devices you should be using.  Good luck!
