I've tried several times to add video and music files to my phone but have only been successful two out of six or seven tries. Most of the time the PC (I've tried two different PC's) won't recognize the disk drive. The two times it did work, when I tried to play the video, the player (on the phone) got locked up and was unresponsive for several minutes. Afterward, the phone functioned very slowly and wouldn't enter the "Personalize" menu... just goes to a black screen. The two times I was able to get media (videos) on the phone it got so bogged down that I decided to erase the phone back to factory settings and start over. The last time around I also formatted the card.
It still isn't recognized by the PC. I decided not to try again as I don't feel like resetting the phone again.
Anyone else having similar problems?
