Roughly about a week ago, Sony released the Firmware 2.20 update. Instead of it updating the system with improved changes and fixes, apparently, it's causing problems when streaming mpeg-4 files.

Over at the official PlayStation forums, those who are afflicted with this problem have already begun airing out their concerns. They noticed that after they updated their consoles, streaming mpeg-4 files wasn't that good. The videos were stuttering to the point that the videos were completely unplayable.

Aside from this, some even posted additional problems that they were experiencing. Streaming mpeg-2 files at 10x, 30x, and 120x speeds run only at a tenth of the designated speeds. Also, users have found out that skipping over unwanted content has become something that was very difficult to do.

Connection issues and media server issues have been ruled out. DivX/XviD files that have a higher bit work just fine. Media servers such as Tversity, Twonky Media and Nero Home Media have all been tested clean.

So what's seriously going on with the Firmware? Well, we'll just have to wait and see until Sony releases something official to immediately resolve this issue. Check up on QJ.NET regularly for updates on this matter.
