Going by my LVW-5045, it is only possible to copy files from its HDD to DVD as a DVD-Video disc. As the copying process runs as quick as its DVD writer is capable of writing to disc, this is a clear sign that no re-encoding process takes place during the copy.
If you have only a handful of titles to copy, I would suggest copying them one by one using a DVD+RW (or full formatted DVD-RW), since the VOB file created on the disc is effectively an MPEG2 file and most MPEG2 editors and Media Players will playback VOB files (or if renamed to .MPG):
- First, get a blank DVD+RW or DVD-RW initialised with full preparation (this saves finalising the disc each time).
- Copy one title to the DVD and then place the disc in the PC.
- Go into the 'VIDEO_TS' folder and copy out the file 'VTS_01_1.VOB'. This is effectively an MPEG2 file of what you copied to the DVD.
- Place the disc back in the recorder and erase the disc before you copy the next title to it.
If you try copying two or more titles to DVD, these will be joined in the VOB file. Also, if the recording is longer than 1GB, it will be split across several VOB files, such as 'VTS_01_1.VOB', 'VTS_01_2.VOB', etc. In this case, you'll need to use an MPEG2 editor to join them. The tool MPG2CUT2 (freeware) works well for me.
