Premiere Pro 7.0 dropping random frames from original video

Question

Here is one of many problems I am running into. When I import original video into Adobe Premiere Pro 7.0 it always leaves out a few frames in random spots scattered throughout a clip (I'm guessing this is what is referred to as dropped frames).
I first noticed this when I went to sync the audio mp3 files, which are imported seperatly, to the video clips and found that the audio clips are a few frames longer; and the audio/video don't match up.
I was hoping someone could shine some light onto why this is happening and what can be done to remedy it. I've fiddled around with differnt settings when loading a new project with no success.
I am importing the origina video from a folder on my desktop. It is MPEG-2 format and came from my Sony Handycam DCR SR45 camcorder. Below are the properties for the video according to a video player on my computer.
Video:
MPEG-2 Video
720x480 (16:9)
29.97fps 9100Kbps
Audio:
Dolby AC3 48000Hz stereo 256Kbps (this audio doesn't show up with imported video files which is why I import seperate mp3 audio)
P.S.
I've recently been told that MPEG-2 files are not ideal for video editing. I've also been told that Premiere Pro doesn't recognize AC3 audio, which is why I am importing the audio seperatly as mp3 files that I have created in another program. Also I've been told that the camcorder I use is not ideal for editing purposes.
So, if anyone sees any reasons to disagree or concur with these statements, please let me know. But, as for right now, I currently have existing video from this camcorder that I MUST make work in Adobe Premiere Pro, so please help me work with what I got. Thanks.

Answer 1

I have began uploading 2 vidoes to the DropBox.
One is the original that came from my camcorder, the other is the attempted converted DV AVI.
The footage is a clip of a turkey hunt i filmed for a friend where a turkey is shot at and missed. The video is not that great but I still need it and other similar clips.
I'm not sure if your familar with Dropbox or not.  We mainly use it for PDF's from architects and Contractors, but I am trying it for video for the first time.  Here is what it states for sharing files publicly:
function(){return A.apply(null,[this].concat($A(arguments)))}
The Public Folder lets you easily share single files in your Dropbox.  Any file you put in this folder gets its own Internet link so that you can share it with others-- even non-Dropbox users!  These links work even if your computer’s turned off. 
Step 1:  Drop a file into the Public folder.
Step 2: Right-click/control-click this file, then choose Dropbox > Copy Public Link. This copies the Internet link to your file so that you can paste it somewhere else.
That's it!  You can now share this file with others: just paste the link into e-mails, instant message conversations, blogs, etc.!

Happy Dropboxing!

Note: You can only link to actual files within your Public Folder, not to folders.
I guess I will try to paste these links now even though they are still uploading.  I will re-paste them later when the upload is complete.

Anyone else who want's to play around with these videos have at it.
I'm glad I found this forum. Thanks for helpin'
