I have the HP z545 MCE PC and a Motorola STB. When changing the channels up\nand down, MCE insists on sending out 3 signals (3 digit channels), and\noccasionally the STB misses one of them, even on the slow IR setting. For\nexample, 120 becomes 12 or 20, and 113 becomes 11 or 13. Is there a way\naround this? The problem is that MCE thinks I'm on channel 120 even though\nI'm getting channel 12, and it doesn't do anything when I re-enter the\nchannel - I have to flip to another channel first before returning.
