Playing with my pronot and just some basic screens to get to know how to use it and make sure evrything works with my equipment as I want it to. Anyway, I've encountered my first problem, when I use either the AV button ot 4:3/16:9 button on my LG TV remote it doesn't scroll through. For instance, if I'm on TV and I press AV it will switch to AV1 but no further. Same with 4:3/16:9, it will go to Zoom then nothing. I have tried pressing quicly or holding, no difference. Strange thing is if when doing the AV button, if I press the button twice on my LG remote, when using the Pronto it will switch twice and continuing going round, i.e press AV and goes through AV1, then to AV2. Press it again and it will go through AV2-S to AV3, etc. Anyway around this problem?
