VOB files from Philips DVDR3330H not accepted


#1

Hi! Playing back VOB files from buyed DVDs works fine, but the Live TV does not playback the VOB files generated by my Philips DVDR3330H Hard Disk Recorder.

I analyzed the VOB files with ffmpeg and MediaInfo - the only difference I found ist that bought DVD VOB files do have BVOP=yes, and the apsect ratio of DVDR3330H’s VOB files is 4:3 wheres bought DVDs have an aspect ratio of 16:9.

IMO, these differences shouldn’t cause differences - any ideas what could be the problem or how I can get WD TV Live to play back the DVDR3330H’s VOB files?

Below the detailed info of MediaInfo:

I further analyzed the problem and found out that it is actually not the VOB file, but the complete DVD structure that WDTV can not handle. If I rename the VIDEO_TS directory, WDTV does not DVD playback, but just VOB playback and that works fine.

Thus, I suspect that there is something in the DVD structure (IFO file) that WDTV is not able to handle (all other DVD players like VLC or WinDVD have no problems with these IFOs).
