I use an easier method that doesn’t require VobEdit and may/may not require DVD2ONE.
1). As you describe, use DVD Decrypter in <F>ile mode to transfer all the files to HDD. Make note of which VTS is the main movie (always the largest size for serial episodic DVD/s).
2). Make another directory called MAIN_MOVIE or whatever, and a subdirectory of VIDEO_TS.
3). Open IfoEdit, open the VTS_xy_0.IFO of the main movie, hit “VOB Extras” then check all but the first and last choices under “Options” and then check the first two and last two under “VOB Expert Options.” VOB Size should be 1 GB. Ignore Angles and Seamless branching. Select the VIDEO_TS directory that you created in step 2 above. “Autocopy menu files to destination” should be checked.
4). Click <OK>. In the next window that appears, select your English or whatever languange, no subtitles. Click “Strip It.”
5). In the next window, click “Select All” to check all VOB ID’s. Then click “Strip It” again.
6). Once that stripped version is complete, open its VIDEO_TS.IFO and click “Get VTS Sectors” as always, again with IfoEdit.
7). If that directory is less than 4.37 GB, well then you are ready to burn. If not, run DVD2ONE on that to resize it down, putting it into another directory that also has a VIDEO_TS subdirectory.
See, this way you only have to run DVD2ONE one time and do not have to join all these episode’s VOB’s. Its much easier and basically gives you the same result.
