Thank you everyone, I'm new to this and I appreciate your patience and advice. Sorry about the name yachtsman1. I should know better being a fellow sailor. Ok, to answer your questions. My laptop runs win8 64 bit. It runs an Intel i5 with 8GB RAM and has both HD and SSD. The audio files are Windows Media Audio files (.wma). Now the good news is that I got it to run smoothly by saving the project as an MP4, HD @ 1280 x 720. Initially I saved it to the wrong screen size but soon realised my mistake. It works on my PC, laptop and both TVs. Interestingly, the file size reduced from 3.6GB (AVI) to 840 MB (MP4), so maybe it was the file size? Thank you nobeefstuI. As you can see, I worked things out before I read your reply but your reference to the guides and Media Player Classic is most helpful. This is a steep learning curve but I'm enjoying it. A bit of background to put things in context. I am a member of a local photography club and primarily use Lightroom and Photoshop. Recently I began using my SLR (both still and video) to capture special occasions for my family / grandchildren and saving them to DVD. That's why I researched and now use PTE. This came to the attention of my wife's art society who asked me to build them a web site and prepare a promotional video for their exhibitions. The web site is up and running (another steep learning curve) and now I have the video. At some stage I would like someone to review the video so that I can learn from a profession critique.
