[mythtv-users] I'm about to give up on this entire thing...

[John Klimek]

The Linux interface (perl script) doesn't work what-so-ever.  So, I've been
testing with only the Windows interface (DTVCON).

I wish I had a port debugger, but unless they are very cheap, it's not worth
it for me to spend money on a one-time project.

What is this "null" that I need in the cable?

Thanks for helping me...
