Weird podcast issue on my iPhone

I have encountered a weird issue on my iPhone. I listen to a bunch of regular podcasts, and have iTunes set to send the 5 most recent unplayed episodes to my phone when synching. Sometimes this means that older ‘casts are on my phone, and if they are news ‘casts, then not so relevant anymore and I want to fast forward through them so the phone marks them as completed.

So as the unwanted podcast is playing, I tap the screen to bring up the slider, move the little dot all the way to the right, podcast is marked as completed, all is well in my world. Unless I am listening to the Xbox 360 Fanboy podcast. Seriously, this is the only ‘cast this won’t work for. I move the slider, there is a slight pause, and then the podcast resumes playing from where it was. Or it jumps to some random location. Sometimes I can get away with moving the slider a tiny bit each time and it will eventually work, but not always. What the hell? Why does this happen with only this podcast?! Yeah, I could hold down the fast forward button, but that takes way too long for a ‘cast that is over an hour long.
