Before I found that example program, I put together a similar but simpler setup to embed an MPEG in an LV panel.
Both the example and my own mock-up display the WMP controls, which operate, but play only audio -- no video -- from all of the MPEG files I've found. Windows Media Player plays the video on the MPEGS just fine if I open them outside LabVIEW. I'm using Windows XP Home and LabVIEW6.1, and have all Windows updates installed. Ideas? Thanks...
