Setting 98 03 0x80 is correct.   just make sure you have the right pixel bus connections as shown in UG-216 Table 77.  The rest of the writes should follow script 6-1f.

If you are not using our eval board then you may have to tweak 98 19, LLC DLL phase adjust to work on your custom board.  The phase delay is board dependent.  You might also tweak 98 14, drive strength, some times you can over drive or under drive the pins causing strange effects, again this is board dependent.

Try testing you system with a non-HDCP source to make sure the HDCP isn't the problem.  When you say little time, what is little?
