Glad to hear it works. Others had reported that it didn't.
I've looked at Mark's latest code and have to warn you that it will make
an improper call to an ivtv driver function, ivtv_reset_ir_gpio(), with
a pointer to a cx18 data structure in the lirc_pvr150.c:write()
function, if the blaster chip stops responding. This *could* have an
adverse effect on the operation of HVR-1600, odds are you'll never
notice what just happened that was wrong.
Attached is a patch I had worked up a while ago to avoid that situation.
Maybe it still applies cleanly to lirc_pvr150.c.
Regards,
Andy
