Trouble with Looping

MPEG files autoplay perfectly the first time, but don't Loop correctly. The hold time on the last frame before the loop varies from about 10 secs to several minutes! From the second play onward the motion is studdery with multiple dropped frames every second.

Problems are the same playing the aq.meg test file included in the BrightSignDemo as they are on my files.

Unit arrived with 1.0.73 sw, and I've reloaded it. Same results.
Autoplayer is 1.0.5

Please propose solution, unit is needed ASAP in museum installation.

  Larry,
  
  
  
  1. Try looping the video using a csv file. Create a simple .csv file named autoplay.csv in excel. To loop one vide named video.mpg, the following would suffice:
  
  
  
  IMAGEMODE 2
  
  
  
  EVENTS videoend
  
  STATE video.mpg video.mpg
  
  
  
  -The first row of your excel file would have IMAGEMODE in the first column, and 2 in the second column.
  
  -Row 2 is blank
  
  -Row 3 starts EVENTS in the first column, column 2 is blank, and column 3 has videoend in all lower case
  
  -Row 4 has STATE in the first column, video.mpg in the second column, and video.mpg in the 3rd column under videoend.
  
  
  
  I will send you a sample file to your email address. Just place the video, the csv file, and the autorun.bas file on the compact flash card.
  
  
  
  2. Even if there's a delay caused by looping using autoplay.mpg, there shouldn't be the shuddering and dropped frames you describe.
  
  
  
  Try reformatting the flash card as fat32. Also, try changing your flash card to a different brand. Some flash cards don't work as well.
  
  
  
  I will also provide you with a location you can upload one of your files to so I can try and duplicate the problem, if the suggestions above don't resolve the issue.

  Thanks for the help. Your workaround with adding the CSV file works. The movie loops with a blackout of only a second or less. And the studdering is gone.
  
  
  
  However this means I have to set up the cards for our exhibit in a way that does not conform to your documentation and may not be understood by the next person working with this material.
  
  
  
  It would be preferrable, if possible, to have corrected versions of the brightsign sw and the autorun.bas file so that the video file could be named "autoplay.vob" according to the documentation and the .csv file could be left out.

  Larry,
  
  
  
  I'm going to email an ftp location I would like you to send one of your files to so I can try to duplicate your problem.
