Blankk screen on playback of recorded cameraroll videos!

[ringonbob]

Hey now,
I have a jailbroken 3GS (3.1.2), been working great. I upgraded 8 upgrades recommended by Cydia last week. Ever since, I can record video and pictures with the camera, but when I playback video from the camera roll, there is audio with a black screen! I can see the video in the thumbnail and thumbnail images in the playback timeline. Videos in the iPod play just fine. The camera recorded videos play back just fine on my computer. Please advise! I appreciate any help!
