The solution I found first is giving inconsistent results. I am getting corrupted files and crashing from Shedworx VoltaicHD.

I have been search all day and found a billion converting programs, and tried a half dozen. Is there a specific one I should be trying?

I have a canon hf200 and windows 7 on a pc. I am trying to get stills out of the video at a high framerate so I follow up with videomach which can do that fine. I own both programs so I am not adverse to buying software if it matters.
 
What codec are you using when encoding your AVI files?

If I'm not mistaken, AVCHD uses the MPEG4/H.264 codec, which is not supported by the AVI container format, so you have to transcode it to something support by AVI.

Assuming you're using DivX or XviD (the most common route), you could use a free tool like Windows Live Movie Maker, or you could pick up an inexpensive video editing package like Adobe Premiere Elements. I'm surprised Canon didn't include any apps for you to use with the camera - their bundled apps are usually very good.

It really depends on how deep you want to go into it. You could probably even go the command-line route and figure out FFMPEG if you're feeling brave.
 
Are you just trying to extract still frames from your AVCHD footage?

AviSynth can do this, assuming you have the necessary DirectShow filters installed (grab ffdshow if not). A script like this should do the trick, assuming you don't need to deinterlace or do any other processing:
Code: 
DirectShowSource("yourvideo.m2ts")  # load video
SelectEvery(30, 0)  # Select 1 frame from every 30 (0, 30, 60 etc.)
ImageWriter("c:\myvideosnaps\", 0, 0, "png")

You could also just use AVISynth or VirtualDub to frameserve the m2ts video to your application of choice. VirtualDub can create an AVI proxy file that will frameserve the decoded video even to applications that can't load AVISynth scripts directly.
