I just bought a 3550A, installed it. It has latest official firmware (1.05). When i play dvds, it seems like the image is playing at around 10 fps, or depending on the dvd player, sometimes just skips. Also, when using PowerDVD, the sound is bad, it scratches. I dont get any of these problems with my normal dvd reader.
Any help would be appreciated.
If you need any additional info, just let me know.
