I converted my .MTS files... all 120 of them....  .... to .mp4 files, then imported those into PD8. The .mp4 files had sound both in preview and in the media viewer. I put all of the .mp4 files into my movie, and then had to re-organize all my transitions and titles, which was really annoying that those are evidently given relative references and not absolute references. The whole movie plays fine with audio, in the previewer and in the viewer. After producing the movie, however, there was no sound. I produced it to an .MTS file H.264 AVCHD file.
Also... the video quality quality was terrible in production, vs the original .MTS files.

VLC player is free, able to read .MTS files, and convert them to MP4 files. I recommend trying this out to determine if the resulting file is playable in PD8. We know that the original is functional. We know that data is extracted and present in the resultting file when processed by PD8. This implies the issue is in PD8s ability to work with the resources available in the machine (available codecs, processing power, etc.). VLC player comes with the requisite codecs to complete the process. At a minimum this test will help more clearly define the root cause.

PS: I have to ask this simply because it has not been asked nor stated explicitly: When attempting to play these files in PD8 you have turned the volume up both in the timeline and on the pc itself?
Do you have multiple sound cards installed, perhaps on the motherboard and in a pci slot?
Will look at VLC.
I've already used other converters, and yes, mp4, WMV, and mpg files converted from my MTS files are playable and editable in PD8. The problem is clearly in how PD8 imports MTS files. It's not importing the audio segment of the file properly. The MTS files should have 256kbps audio in Dolby Digital. I click on file properties, and PD8 will list the video and audo codecs and bitrates properly.
The volume is set to max, in windows, and in PD8
sound cards: no, I use a laptop, i3-2330, integrated gfx intel HD3000.

I want to make sure I understand this part: When you state 'appear blank' does this mean you have saved the resulting file as a .wav and attempted to play it on an independent media app such as VLC player? If so please answer the following:
- What was the resulting file size of the .wav file?
- When played does the progress bar advance at the expected rate?
I am ignorant of working with MTS files, and all but ignorant of PD8 on Win7 so I apologize if the following is tedious or not logical relative to process:
I have encountered a similar issue to this working with 'Garage Band' project files from a friend. The project files appear as zip archives in Windows and the mix down file has a .xyz extension which could not be imported/read by PD. I changed the file ext to mp3 and PD would import it, but no audio would play. I could play the resulting file just fine in VLC player but nothing in PD. So I imported the file into nero recode, converted it to a .WAV, and suddenly everything worked.
What I believe is at play here and in your scenario is unrecognizable data, missing expected data, or simply variable bit rate issues associated with the MTS file rendering PD 'speechless'. The conversion process resolves this as it writes the data in the predicted format.
I hope this helps.

The resulting .wav after "extract audio" is 9mb.
When playing the .wav in WMP yes, it has a progress bar, but no sound. Just like in PD8, the files all play, and have a progress bar, but have no sound. In the timeline view, you can opt to view wave form, or not, for audio. The waveform is flat. The very same .MTS files play in WMP just fine, with audio, direct from the SD card.

same/similar issue. I have PowerDirector 8 trial version 8.00.3306 in Win 7.
No, I'm not upgrading, unless there is a more recent trial version that will run on Win7. This is the first time I've tried using this on my old laptop for family vacation video editing and turning clips into 1 continuous movie.
I've imported 120 *.MTS clips from my sony video camera (SC card, AVCHD files, H.264), and there's no sound in the preview, no sound in the player, no sound in clips, no sound in my movie, no sound after production. I can right click on each clip in the Editing pane and the media room, and "extract audio" as a .wav file from each .MTS file, but those also appear blank, silent, no waveform, no audio. When I add those .wave files as a voice or music track, there is no sound.
I can play each .MTS file from my SD card in Windows Media Player (WMP) just fine. They have audio. When i play the extracted .wav file from PD8 in WMP , it too is silent.
