Can I watch realplayer video on my iPhone?

unless there’s an app. that supports it…no

you can convert them depending on the file type. You can use popcorn or crunch by roxio. Or a MPEG streaming that’s freeware to convert.

that’s if you can capture the video

Download the video wherever possible, and get SUPER© [freeware] which can convert just about anything into ipod format, you just have to import it into your itunes.

Otherwise, no.

Yeah, I can’t find a video converter for mac though. That’s been my problem.
