Yes, my sec post, but this time i suggest to all yours how i receive/monitoring iR signal...
First a piece of software very usefull (search by google, don´t know if can post link) called digitrace from JWA systems (maybe almost of yours know them)...
Second, search an 5volts adapter, connect them to an iR modulator and receive his signal trougth parallel port, setup soft and make trigger for the channel you use...
Third enjoy....
