Sure, 4:3 and 16:9 are ‘Basic’ Aspect Ratio Settings (in the Setup Menu) and there needs to be a Button on the WD Remote to Switch… but there needs to be More Options for Aspect Ratio.
Personally, i own a Panasonic TV which has a “Aspect Ratio” Button on the Remote.
Which supports, 16:9, 4:3, 14:9, Just, Zoom1, Zoom2
Thank goodness for that,
because aspect changing for the WDTV has been asked for many times, by many people…
it was even posted a YEAR ago in the Ideas section.
HDMI1 and HDMI3 … Support 16:9, 4:3, 14:9, Just, Zoom1, Zoom2
HDMI2 only Supports 16:9 & 4:3 (There is a Technical Reason for this, but haven’t delved into it)
So, if on your TV Remote you Press the Button that control the TV’s Aspect Ratio and you only get the choice of 16:9 and 4:3… Switch OFF your TV at the Main Power Switch on the TV (not the Power Point) and don’t turn off your WDTV.
Unplug and Replug the HDMI cable into another HDMI input and Turn your TV on, and on the TV Remote select the appropriate HDMI Input… and then try the Aspect Ratio button again on your TV Remote.
