I am having a lot of trouble getting trick mode to display images on my Roku. I created a directory of images from my video, as recommended in http://forums.roku.com/viewtopic.php?t=23520, and I ran biftool, also as suggested in the link. I then hardcoded the bif file into my bright script. I know this link is correct because I have copied it directly out of the code into my web browser, and it downloads correctly. I can even extract it using biftool after download. The URL to the biftool is placed in the variables HDBifUrl and SDBifUrl. When I rewind/fast foward, there are no trick mode images.
I'm out of ideas, what else could be stopping this from working?
One more thing: the video player example does not have trick mode support.
