• Increased the minimum in-memory video buffer to 128 MB on devices with under 2.4 GB RAM.
• Kept a 256 MB minimum buffer for devices with 2.4 GB RAM or more.
• Removed the redundant sub-1.25 GB RAM playback profile.
• Standardized playback buffering on all devices: 5 seconds before starting and 10 seconds before resuming after rebuffering.
• Prevented disk prefetching from competing with the active video stream while the main player buffer is still loading.
