Streaming Video from External Sources... Specifics?

[USMC2Hard4U]

I recently ripped a few DVD's and converted them to MP4 H264 Files just to play around (I use handbrake for the Mac works wonderfully) Anyway, I was wondering what kind of bandwidth etc I really have or get with certain devices such as USB2 and Firewire. I know the "Specs" but we all know that most of the time these devices dont perform as they are advertised.

For example, I ripped Star Trek 2 the Wrath of Khan Into a Extremly High Quality H264 Movie. This movie is encoded as a H264 MP4 file, and it actually looks better than the DVD side by side, due to shaprening filetrs etc. Well the file is 17.2GB, and the KBPS rate of the Movie is about 23,000kbps. While playing this file from my USB2 external hard drive, it skips often, almost its not being accessed fast enough. However when I play it from my internal HDD, no issues at all....

What could be my issue? I know the advertised specs of USB2 are surely faster than 23,000kbps.

Thanks

yes advertised speed for usb is about 400mb/s so 50 megs/s the actuall speed is closer to 20-25 which is why your movie staggers, the encoding rate is way to high for usb. Go with esata external drive if you want to stream movies like that.
BTW an average 720p h264 mkv tvrip only needs about 4-5MB/s to be smooth
