Not at all. I just used the regular update button if there was an update from vero. Same with my tv. I also had the same problem too on my old tv on random movies or series. I really miss a button which they had in wd media player where you can place the subtitles higher or lower in the movie.
If you plug a keyboard into your Vero you can press ctrl+T until it changes to “fixed” and then you can use ctrl+[up arrow] and ctrl+[down arrow] to move the position up and down respectively. If you have keys available on your remote during playback they can probably be mapped to this task (I didn’t look).
While it’s a bit of a fiddle, you can do this without a keyboard too. Under Settings->Player->Language in the main menus, set the subtitle position to Fixed. Then, when the video is playing, bring up the On Screen Display, go into Video Settings, scroll down and select Video Calibration. Click OK to go past the first two options without changing anything; then, on the third calibration screen you can set the vertical position of subtitles. Then click Back until you’re back in the video.
