UPDATE- 6-4-10 12:15PM Central. The dev just released another update, a fix for the DI. This removes the thumbnails and solves the problem. It now works as it did before. I applaud the dev's quick turnaround. He got out an update within about 3 hours after my initial email. Just a heads up, if you have the Act1 Video Player, DO NOT UPDATE. (UPDATE 6-4-10) It adds thumbnails to the videos which destroys the app. Here's the summary I sent to the developer:The app opens as fast as it always has. I have 3 folders with videos on them, 1 internal, 2 SD. They have 3-4 videos each. Pressing anyone, there is a 3-10 second lag until the files and thumbnails show up, longer if one folder is already expanded. The thumbnails are incorrect for some files, correct for others. With folders expanded, the app becomes unresponsive after a while. Opening a file takes about 10-15 seconds, if even successful. Playback seems fine, although scrubbing takes a little while to get going at first. The dev responded very quickly, and is working on an update for the DI. I have the Pro version (paid). It was working great, and I recommend it for those looking for an actual video player, once it gets fixed.
