Not really a full failure, but very frustrating -- yesterday I loaded some respooled Kodak movie film that I had managed to get my hands on into my N80 (wanted shoot some nice shots of my girlfriend before she left for a month on a work trip), but it jammed after the first shot. At first I thought I had misloaded it and it was my fault, but decided to waste the first couple frames by opening the back to check, and I hadn't misloaded it. So I tried rewinding it to try again but it rewound the feeder all the way into the roll so now I'll have to find someone with a film puller. Not a huge disaster, but a frustrating inconvenience nonetheless...
