Thanks...I tried this code but all I get is an alert that a Pronto code must start with "0000". Transposing the first two "bytes" did not work, either.

Followup...The above result was through NEOhacker only.

I later tried the Pronto2NeoConverter. One of the codes it suggested selects the AV1 input; the others do not work. The elusive code should bring up the Next Source menu. But if I can get codes that can directly select any of the six possible inputs (AV1, AV2, AV3. HDMI1, HDMI2, and Side), so much the better. Thanks!
