Till today, no one has called me from Motorola (Singtel said they will ask them to call) to rectify the HDMI issue.
After reading some forums out there like xtremeplace and ocworkbench, I noticed that i am not alone with the HDMI issue.
Rather than meddling with HDMI, I tested it using Component Video. Alas, so far so good. At least the box won't auto reboot or give me a half pink screen after waking the set top box up from standby mode.
One thing I still don't like about MioTV box is that it takes around 2 minute to BOOT UP! That is way too ridiculous. Starhub box only took at the most 10 secs. If i were to watch an important news, I would be watching the 9.02pm news instead of 9pm news since I will be spending my time, waiting for the box to boot up after powering up.
If they don't resolve all these issues, I think it is time to say goodbye to mio. It is too problematic and not ready.
