Have you joined the discord channels already?
There's a @dtube chat where you can address (technical) questions like that. I'm pretty sure the developers will be happy to help. If you don't have received an invitation to the server yet, just drop me a message at steemit.chat and I send you an invitation link :-)
Regarding "driving and talking": I really didn't expect this to become an issue here. What about free-hands car kits that are used for GPS systems, touchpads, phones, etc. My GoPro is fixed and I control it via voice control, so there is zero interference in my driving... But anyways, I learned that I won't ever publish vlogs from a car anymore - not because I don't want to do it, but because of the community's preoccupation :-)
I haven't joined discord yet. I need to do that, esp. if they can help with the buffering.
