I recently had to replace the motherboard when the original one locked up and have the replacement working OK except for subtitle duiring play of a recorded file.

Invoking subtitle mutes the sound during play for several seconds, then after a bit audio is restored and the subtitles appear. Play procedes as normal otherwise during this process with video unaffected. This does not happen with the Solo2 and did not occur with the Duo 2 seven months ago (an earlier VIX installation) so I'm wondering if I have accidentally set up something incorrectly or is it a bug in the recent software?

As my hearing in old age is now quite compromised I need subtitles constantly so would appreciate any help as this is most annoying.

TIA
