When upgrading to astro beyond, can i refuse to give the old smart card ? because every time i go back to my grandmother's house i will take the card to watch my subscribed channel at there and will the card work after i upgrade to astro beyond? thx

Not either one, old smart card must be returned. It will be useless to keep it though, it won't work after your byond smart card activated.
Byond smart card will only work with your byond decoder only. So, when you go to your grandma house, bring byond decoder as well (don't forget power adapter as well). It'll work with old dish.

I wouldn't mind if other satellite company other than Astro opens up for competition. One satellite is not enough...

just to share with regards to 3D:

Samsung issues 3D TV warning

Television viewers will soon be able to watch sport and films in 3D format, but a stark safety warning issued by the world’s largest TV maker may turn some would-be buyers from the technology.

Samsung Electronics said in a long safety guideline on its website that viewers of 3D TV could suffer epileptic seizures and strokes.

It also said sleep deprivation or consumption of alcohol while watching 3D programmes could be unsafe. The South Korean company said on its Australian website pregnant women and the elderly should avoid the 3D function, and children and teenagers were more susceptible to health risks.
