Hello,
I have been trying to program an old WebTV Keyboard (Sony Plus model, pre-Microsoft) but it appears that some of the keys are grouped together such as Q & R using the same IR code while E &R using their own. \
Unless there is a trick with sensitivity I do not think this keyboard is compatible.
I am wondering if other WebTV keyboards would work such as the Phillips
or RCA (newer "MSN TV" version)
The regular remote (sony) on the other hand is working for me so far:
