1A/1Z has no video capability.
He’s talking about using the DAPs with a laptop for movies, as there is a slight delay which causes speech to not sync. So instead of using a direct DAC mode, which is obviously best SQ, you switch to Bluetooth and the delay is no longer an issue.

There are two work-arounds. One is movie playback software that lets you move the audio sync-point forward or backwards. I just go Bluetooth and it’s fine.
for movie its not really important since can just use the LDAC, but when watching Music Video, the difference is too much to ignore, DAC mode give alot of details and resolution, much lower floor noise.

I bought a spare battery before, and yes, they are the same.

The hardest part is to remove the battery and solder in the new one....you do not want to short the “terminals” out at all. It can blow in your face!!!

that is totally serious and no joke

Totally agree, although the wires do come pre-tinned and the live terminal has a protective plastic sleeve over it which should only be removed immediately prior to soldering. The other danger is shorting the live terminal against the chassis via the soldering iron - definitely a job for a steady hand!

...and I think they can order pretty much any parts you require. Shipping was about two weeks for me.

If you are going to do this yourself (or get a non Sony engineer to do it), I strongly suggest that they review the maintenance manual. There are a few double sided adhesive strips that you'll likely need to replace. They are all indicated in the manual though. Good luck!!!!
