Support for reading files > 4gb from sd card

[helpjimmyout]

Hello everyone,

I've been reading into this all night and now my head hurts a bit. I'm having an issue getting what I want with this phone. My goal is to copy an HD video file (~5gb) from my computer onto my phone and then play that video on my TV using the HDMI out feature. I figured this would be a breeze to do when I first got my phone, but the issue with file systems is really getting me screwed up.

First, is my goal possible?

Second, what is the best way to get to my goal? I have so far tried to format my SD card in ext2/3/4 and exFat, none of which are detected by the RAZR. I thought ext3 support was built into Gingerbread. What's going on here.

If it helps with anything, I rooted my phone.
