1. This has nothing to do with IrScrutinizer. You would not ask Apple or Samsung about a "silly" phone number...
2. IrScrutinizer understands hexadecimal numbers in 0x... notation too,
3. ... and contains a hex <-> decimal converter (Tools -> Hex calculator).
4. Your options are:
* Guess how the numbers should be transformed to S, D, and F,
* Find the codes somewhere else (https://irdb.globalcache.com ?)
* Capture them yourself. For this, Smakodak make a good offer; take advantage of that.
