I am very grateful for your time and effort on my behalf.
I see what you say regarding quality. I do not know why the resolution is so low, almost as if from a video camera (old).
The original recordings were high speed copied to the DVD from the old recorder and provided the Video_ts folder I now have. They took 20 minutes to copy 6 hours and finalize and presumably they are originally stored on the recorder HDD in the same form, but don't know how to actually access them any other way.
The vob files are typically 1.3GB per film against uncompressed about 11GB per hour. Any changes in
I have just opened another DVD at random from the same HDD/DVD recorder and it contains a folder DVD_RTAV in which is VR_MANGR.IFO & VR_MOVIE.VRO 4.2GB 3hr 17mins.
??? it locks up Mediainfo.
The only other thing I can add is that recordings to HDD were invariably done at longest play to get max time and then 6hrs placed on each DVD
There's two problems.
1 The recording you opened has been made in a format that you can modify after recording (Usually called VR mode). They should have been made in DVD-Video format.

2 Using longest play means maximum compression hence low bitrates and the major reduction in resolution. A single layer DVD blank can hold at best around 2hrs of good quality SD content and about 20-30 minutes of 1080i in AVCHD format. Full quality mpeg2 576i should use about 2GB for each hour of recording. You have 6hrs in about 4GB.
Have you still got access to the original source of the video ?.
