can the astro pvr 500 gb hard disk be formated to ntfs, no more use the astro pvr.

also, one good benefit is a tablet need not use an air mouse, using finger to operate is easier for old and computer-illiterate people isn't it?

yeah it'd be a bit more troublesome. the main issue here is that old people like my parents are computer-illiterate and never know how to use a mouse, so i'm trying to see if my new solution can totally avoid using mouse or not.

another issue is whether it is practical or not to run the tablet for more that 4 hours with an active connection to wifi and TV. Has anyone done it before? Any advice?

Eventually i got this box https://forum.lowyat.net/topic/2920813
Now my parent can watch Zhejiang TV. Tested 1 day only. So far so good. As it is mainly in chinese, it is suitable for them and not me.

Using airmouse..point and click. Must be easy to navigate else my parent will suffer and eventually myself...hahaha
