Next, the format mentioned is BD (Blu-ray). Normally, BDs are high-quality discs, but they're usually in 480p? Wait, 480p is actually a standard definition resolution and not typically associated with Blu-ray, which is much higher. So maybe that's another confusion. The user might be mixing up different quality standards. BDs are usually 1080p or higher, while 480p is DVD-level quality. Maybe they meant 720p or 1080p instead of BD. Or perhaps they're referring to a DVD (Digital Versatile Disc) in 480p, which is more common. Alternatively, the "BD" could be a typo for "DVD."
