5003: 1USB, 2HDMI (Kent888 mentioned there is only 1 HDMI, will check it out, as the website is from Philippines)

I/O: 5000 has headphone jack, Ethernet LAN

Extra feautres of 5000
AnyNet (DLNA)
TeleText (TTXT)
Auto Channel Search
SRS Trusurround HD
Ultra Slim Wall Mount Support available

There is actually a Indonesia/Philippines model 5030

Anyone knows which Eletrical shop has 5030? Which can be cheaper than 5000 but having nearly the same feature of 5000.

price of D5000 had dropped to around RM2.2K so I guess you can get D5003 for less than 1.8K
if you have your own media player and do not need more than 2 HDMI and 1 USB input, DLNA, it's good value
