Tonight, I again confirmed what I had learned several months ago when I worked with a Panasonic DMR-E30:
No re-encoding will occur when burning Panasonic player/recorder MPEG files - even with Ulead software that doesn't officially support AC-3 audio.
Ulead VideoStudio 7...
...doesn't officially support AC-3 encoding.
Tonight, however, I visited my local Ultimate Electronics store.
I brought a blank DVD-RAM disc with me and the salesman was more than happy to demonstrate the new Panasonic DMR-E50 player/recorder model.
We recorded a few seconds of video.
I then took the disc home and inserted it into my Panasonic computer drive - an SW-9571.
These are the exact steps I took to extract the MPEG from the DVD-RAM disc and then create menus in Ulead VideoStudio 7's DVD authoring module and then burn the file to a DVD-RW disc WITHOUT RE-ENCODING:
1. I opened Ulead VideoStudio 7.0;
2. I inserted the DVD-RAM disc with the Panasonic DMR-E50 recording into my Panasonic computer drive - the SW-9571;
3. In Ulead VideoStudio 7.0, I selected FILE > CHANGE CAPTURE PLUG-IN and I selected the ULEAD DVD-VR CAPTURE PLUG-IN;
4. I then clicked Ulead VideoStudio 7.0's CAPTURE step button;
5. I then clicked the OPTIONS icon and then clicked VIDEO PROPERTIES and browsed to the DVD_RTAV folder on my DVD-RAM disc;
6. I then clicked the CAPTURE icon button and a pop-up screen appeared with a thumbnail representing the video that was recorded by the Panasonic DMR-E50;
7. I clicked on the thumbnail and then clicked FINISH to 'capture' the file to the Ulead VideoStudio 7.0 timeline;
8. I then observed the file's properties by right mouse clicking on it:
VIDEO -
FORMAT: 24 BITS, 704 x 480
COMPRESSION: NTSC DVD, FIELD B, VBR, 9556 Maximum Bit Rate
FRAME RATE: 29.97
TOTAL FRAMES: 1201
AUDIO -
FORMAT: DOLBY DIGITAL AUDIO
ATTRIBUTES: 48000HZ
9. During Ulead VideoStudio 7's EDIT button step, I then clicked the EXPORT button;
10. After clicking the EXPORT button, I clicked the Ulead DVD-VR Wizard;
11. I did so because I wanted to observe the pop-up to see where the program was temporarily storing the extracted MPEG file;
12. The pop-up revealed the file had been given a name - uvs030721-001.MPG and was stored here:
D:\Temporary\uvs030721-001.MPG
13. I then cancelled the Ulead DVD-VR Wizard;
14. I then clicked the SHARE step button and then clicked CREATE DISC, causing the Ulead VideoStudio 7 DVD authoring module to appear;
15. Having earlier made note of the location of the extracted MPEG file, I clicked the ADD VIDEO button and browsed to the file to import it;
16. I received this three-line message:
"[D:\Temporary\uvs030721-001.MPG] contains AC-3 audio tracks."
"Ulead VideoStudio does not support this audio format."
"Please convert the audio first to a compatible format."
17. I ignored the message and clicked OK.
18. I then clicked the button in the lower left hand corner of the authoring module interface and set my DISC TEMPLATE MANAGER AS FOLLOWS:
MPEG files
24 Bits, 720 x 480, 29.97 fps
Field Order B
(DVD-NTSC), 4:3
Video data rate: Variable (Max. 9556 kbps)
Audio data rate: 224 kbps
MPEG audio layer 2, 48 KHz, Stereo
19. I then clicked the other button - the one with the large CHECK - in the lower left hand corner of the interface to adjust my PROJECT SETTINGS as follows:
MPEG files
24 Bits, 704 x 480, 29.97 fps
Field Order B
(DVD-NTSC), 4:3
Video data rate: Variable (Max. 9556 kbps)
Audio data rate: 224 kbps
MPEG audio layer 2, 48 KHz, Stereo
20. I also checked the DO NOT CONVERT COMPLIANT FILES box;
21. I then clicked the NEXT button and chose my menu;
22. I then clicked the NEXT button and tested the menu on the software player;
23. I then clicked the NEXT button and arrived at the final burn page;
24. At this point, I ejected the DVD-RAM disc from my Panasonic drive and I inserted a clean DVD-RW disc;
25. I then clicked the OUTPUT button to burn the disc;
26. After the disc was finished, I checked to make sure the AC-3 audio had 'passed through' without re-encoding to either LPCM or MPEG Audio by closing the authoring module and then clicking the CAPTURE button step in Ulead VideoStudio;
27. I again made certain the Ulead DVD-VR Capture Plug-In was selected and I browsed to the location of the Video_TS folder on the burned disc;
28. I then clicked the CAPTURE button and the pop-up confirmed the file's properties as follows:
Video :
MPEG-2 Video
4:3 Ratio
704 x 480 Size
1201 Frames
9556 Kbits/sec
Audio :
Dolby AC-3 Audio
stereo Mode
48.00 kHz
2 Channel(s)
IT WORKED!
So - as you can see - one *can* use Ulead VideoStudio 7 and Ulead DVD MovieFactory 2 to burn AC-3 MPEGs recorded in Panasonic player/recorders - and burn the material to disc with nice menus - WITHOUT RE-ENCODING!
Good news for Panasonic player/recorder owners!

P.S. This method assumes you don't wish to *edit* the MPEGs.
If you wish to edit the MPEGs, then you'll need to upgrade to either Ulead DVD Workshop AC-3...
...or Ulead MediaStudio Pro 7.0...
No re-encoding will occur when burning Panasonic player/recorder MPEG files - even with Ulead software that doesn't officially support AC-3 audio.
