MCE Remote and blasting your Set-top Box

    After reading abit on the subject I think I figured out how to blast my
    Samsung STB - at full speeed. It's a abit interesting since it is
    contradictory to how MCE thinks it should work.. I played with the Samsung
    remote for the STB and saw something peculiar:

    * If I hit zero(s) first and then a digit, the STB would not change a
    channel, it's confused by any leading zeros. (OSD pops up with the new
    channel number but it will not change to the new channel) If you do this
    VERY slow, it works but that is unacceptable in my book.

    * If I hit just digits then follow with the OK button, the STB would also
    NOT change the channel, same issue. (OSD pops up with the new channel
    number but it will not change channel)

    So in essence, both methods suggested in MCE for blasting my Samsung STB are
    really wrong in my opinion:

    * It asks if you hit OK/Enter to change channel: if you say NO, then it
    enters leading zero(s) depending on how many digits/channels you
    configured. However, this behaviour of blasting leading zero(s) confuses
    the STB. (Unless VERY SLOW ir blasting) This can be confirmed with the
    original Samsung STB remote. You need to hit numbers sequentially fast to
    see this behaviour <---an important detail

    * The MCE opposite, ie stating YES: "I do hit OK/Enter to change channels",
    means also that MCE will not transmit leading zeros. Instead MCE finishes
    with an OK key. Now, the Samung STB does not expect/want an OK key press
    at the end EITHER. (Even though it has an OK button in the middle of 4
    arrows only for OSD type navigation, like most other remotes, but it
    confuses the STB exactly as leading zero(s) do. You need to hit numbers
    sequentially fast to see this behaviour <---an important detail

    So what to do then?
    I thought a bit about this...the MCE folks seemed to have decided that it
    needs to either embedd (zero) digits in front or or an OK key at the end
    of the trasmission, especially if you want fast IR speeds which is a
    "requirement" in my book.

    I simply used another brand remote to send an arbitrary code for the OK key,
    which the Samsung STB happily ignores. Now it works, even at the default
    high IR speed!
