On mine they are always in the correct place. I was under the assumption that you had moved them up without knowing how… Mine appear in the correct location.
Many people complained about subtitles being CUT OFF on the bottom because their TVs had too much overscan. I imagine WD tweaked the default up a little bit to prevent that…
My subtitles are in the middle , i did not change positions or so, just installed the latest firmware.
Never was in the middle before upgrade.
Even when playing a Panavision movie WIDE and VERY small, it overlaps the movie at the bottom by a full line, while almost HALF of the TV screen (54 inch) is black at the bottom.
WDTVLIVE - maybe its box-depended that upgrades go wrong on some box-series… problem remains however with my box.
