The issue happens on all video in SLR drive, with standalone Quest 2.
Some videos I recently tested:

After my previous comment post, I have tested on Quest 2 (Linked by PCVR with cable) and the issue did not happen (i.e. didnt freeze every few seconds). But the videos loaded quite slowly despite my network is very fast.
In light of the above, I suspect the issue is related to the server of the SLR drive.
