I finished creating my video session and tried to render for a Blu-ray disc. Once during the creation process the session stalled and I was told to do a "save as", I did that but I think it didn't fix the problem, When it gets to about 3/4 from the end it stops and gives me an error message about low memory, I have 16 GB of memory and I'm not running any other programs at the time. I tested to see if it was the Vegas program was having a problem, I render a older session and it worked. Thanks for your help. Ozzie62
