Hi, I have the same HUGE problem.
This is the second time this month. So I cannot wor !!!:
I use newest V 6.01. I describe this problem:
If I edit a video (MP4) and export the edited video (HD YouTube MP4 etc normal format), then I CAN see this video at all videobrowsers.
BUT: if I enter this video in Videopad V 6.01 and play this video, then this video only shows the first "pic" and freezes, while the audio play normal.
At the Videopad TIMELINE for sequence and for clip, I only see ONE "PIC" (the first "pic" at the beginning) .
This is not the first time OI have this problem and it frustates because I cannot edit created files anymore!
