Serial? -- WAS: Hauppauge WinTV PVR - lircd - could not open /dev/lirc

[zeek <ze...@sp...>]

Greetings,

I've been putting far too much effort in getting the IR on this Hauppauge to
work with LIRC (boring details with some developments below). I only want to
experiment with IR control with this card (as a prototype) so I'm wondering:

1) What is the most established, hassle free way of getting LIRC to work?
Serial receiver?
2) That is, does someone have an inexpensive product (homebrew or not),
Serial receiver compatible with touchscreen remotes? Yeah, the Pronto is
really nice but something <$100. I've seen some attractive Sony devices.

Basically I've got to get a move on with some technical info and a solution
as to how to build a prototype digital jukebox (and eventually HTPC on
Linux). The budget is small but I'm willing to work with you. If you can
couple the receiver with display output, please email me immediately. 

Have no hesitation about tech-speak or details as I've been working with
Linux nearly since Linus announced it (pre 1. kernel, 12+ years?). However I
do need speed with a solution as I'm in a stressful positon of tech,
potential marketing, sales, and so on. 

Thank you,
-zeek
