Hello,
Which version are you using, 1.0.5 or beta 1.1.0?
You can click "Global Setting" (⚙️) to check the version number.
Regarding the crash issue, is it possible that your Quest 2 runs out of battery after approximately 2 hours?
As for the renaming problem, which DLNA server are you using? Generally speaking, only particular DLNA servers will rename the files. SKYBOX doesn't have the automatic renaming feature.
Best regards,
Lucy
