Hey guys I am trying to decide between the 700bt and the 900bt. The only reason I want the 900bt is because of the dvd player. However I was wondering if I can do the following the the 700bt.

I have a 1TB external hard drive. It has 2 partitions one of which is fat32 (for my ps3). This partition has all of my music and movies. If I hook up this HD to the 700bt will it be able to play the movies??? Most of the movies are in avi format. they play perfectly on the ps3 so I was hoping it would work on the 700bt. Let me know if this is possible and more importantly easy to do. Thanks in advance.

Also are there any other major differences between the 900 and 700??

I was wandering the same thing i found a cheap ext hard drive on ebay and my harddrive on my laptop is filling up with movies and videos anyone tried it?

Making the jump to iPod is highly recommended. External HDD's are a hit and miss afair. I had a 40GB 2.5" drive that worked fine in by 8000BT (non touch screen) but my F700 would not recognize it, even with external power. After reading about the iPod features (quick boot times, album artwork, easier navigation, etc.) I recently bought an iPod Classic and haven't regretted it.

yea but the reason why I wanted the external hook-up is not for music. Its for movies and the ipod can only play mpeg4 files (videos) while my external can play avi files which is 95% of my video files.

You are able to hook up an external hardrive to the pioneer navs, however there is a GB capacity. It is well below 1TB. Off the top of my head i believe it is 250gb or maybe just 200gb and it has to be FAT or FAT32.
