If you're having trouble playing a Blu-ray Disc made with VEGAS Pro or DVD Architect Pro, the problem is likely not with the disc itself. 

If the burn process completes without any errors, the disc is probably fine. Blu-ray Discs made with VEGAS Pro or DVD Architect Pro should play in all players that support BD-R and BD-RW discs.

The following tips may help resolve playback issues:

1. Make sure you are using the latest drivers and firmware for your Blu-ray burner and player.  Check your Blu-ray player's manual to see if it can play BD-R or BD-RW discs. Some players require a firmware update to do this.
2. Make sure you are using the latest version of VEGAS Pro or DVD Architect Pro. To do this, go "Help" > "About" to see which version you have installed.
3. If possible, try playing the disc on a different Blu-ray player.
