i don't have such problem of "send個'Power On/Off' signal比個TV" the tv itself just switch to other input instead of switch off itself, but i agree that the only downside is you have to leave all the equipment into standby mode instead od switch off the main power to save energy.
i have 525 bought at last year but still not use........
i think will open this week...hehe
so can control the air conditioner remote with 525??
pls advise........thanks
