It should go to a page which informs you of the status of the processing, if you've just clicked "Convert" you should have two possible results:

1) "VidConvert Results" - it's either in-processing (and the progress will be shown), or the resulting AVI will be shown.

2) "Please wait" - you're in the queue, and will be processed in turn.

Absolutely nothing happening is very strange. How big is the file on your 770? Could you email it me so I can try?

Thanks in advance, and sorry for the inconvenience.

Cheers,

Andrew
