CheapB: According to the specs on B&O website, some 3rd party protocols seems to be supported, but the Beo5 does not transmit IR in the feq needed for most 3rd party products without additional hardware - it only supports 455khz and 2080khz. http://www.bang-olufsen.com/page.asp?id=373&productid=365 I think that should be 455 kHz, and 20 to 80

Shift changes the key code (last 2 digits), link sets a bit... 11:00191 A.TAPE 11:00194 A.TAPE2 (SHIFT + A.TAPE) 11:10191 LINK + A.TAPE 11:10194 L-A.TP2 (Beo4) 11:00091 AV + A.TAPE (Beo4) number_of_bits:data (both in hexadecimal)

Here is what I know about Pronto B&O codes in the 7000 format. Maybe someone else can decipher the unknown parts. This is how the Prono hex maps to pulse times and what they mean... 0005 = T1 3.125 mS = 0 bit 0004 = T2 6.250 mS = Same as last bit 0003 = T3 9.375 mS = 1 bit 0002 = T4 12.50 mS = Stop bit 0001 = T5 15.62 mS = Start bit So... 7000 Special
