I have a Yu-xing 6911H TV decoder, as used by NowTV in Hong Kong, and am having problems with two of the learned codes. My Pronto Pro NG learns most of the functions ok with a duration of 0.1 sec, but learned codes for 'Display' and the '8' digit on the keypad do not work regardless of the duration I set. The hex codes learned by the Pronto Pro NG are as follows:

Other learned hex codes that DO work are as follows:

I've tried researching various IR protocols, but can't work out what's wrong. Can any of the hex code experts out there see the problem? I'd be immensely grateful.

Problem solved!

For what it's worth I used IR Tool and found that the remote is using XMP protocol with a device code of 73.17. The learned codes for 'Display' and '8' were garbage but I was able to determine the correct function codes (11 and 86 respectively) using the output from IR Tool and converting the relevant part of the hex dump to decimal (Thanks to JohnSFine for the explanation he provided in another thread). From there, I used MakeHex to generate the correct hex codes.
