I have just stripped out a lot of recordings from my Panasonic DVDR by copying to a DVD-RAM disc, and then copying to PC
The typical format is a VR_MNGR files (.IFO file) and the combined video & audio file VR_MOVIE (.VRO file)
The files will play on PC if I use VLC .. so getting them off the DVDR has at least worked.
I have 2 questions that may well link ...
For some of the larger recordings, I had to split it on the DVDR in order to fit on the single sided 4.7GB DVD-RAM discs, so consequently for some recordings I have sets of VR_MNGR & VR_MOVIE files ... all same names but I have copied into separate part a, part b folders etc.
It would be nice to join them back up to single files ... is there a suitable piece of freeware that can do this, thought I would be able to use VirtualDub but it does not support .VRO
Secondly to aid watching them with ease (on TV for example) .. thinking that if I could convert to MKV that might be easiest , I can then simply put onto a USB flash drive to watch wherever.
I could as a plan B .. drop the files into Sony Vegas, simply joining appropriate segments, and then 'render as' creating and mpg file or similar (no MKV option) .... just the render process will take a lot of time, and in effect I am then transcoding all files ... is there a simpler way.

Where are your .mov files? Change the thread title(click on edit and go advanced) and you might get some better help.
You could try rename them to vob/mpg and see if you can load them directly in mkvmergegui (included in mkvtoolnix). -
Not sure why I put MOV in subject line must have been thinking of movies. - corrected

Using this https://www.videohelp.com/tools/DVDVob2Mpg should allow you to convert your vro files to mpg

After some intensive Googling came across CUDA Videconverter 7 (free)
This does accept .VRO files ........ and has a whole host of output formats .. including MKV, and has built in merge ... capability
I just tried one .VRO to .MKV .. but was surprised that the MKV files was more than 2 X the files size of the .VRO
For example inputs files 1.94 GB and 3.74GB ... merged and converted to MKV 12.4GB
That is a very hefty overhead going from VRO to MKV ... -
Lower the video bitrate to get smaller size.
But you shouldn't need to reconvert. You can put vro(mpeg2) in a mkv. Did you try dvdvob2mpg and then put the mpg in a mkv with mkvtoolnix. -
To repeat what has been said.
Your vro files are 'wrapped' mpeg2. Use the suggested tool to extract that mpeg2 file - no re-encoding so file size is more or less the same.
Then use the other suggested tool to create the mkv. Again no re-enconding.
The problem with these free converters is that you can have little control over what they do( yu could even end up installing some nasties on your PC - nothing is 'free'). You might end up with that mkv file but is it still a mpeg2 wrapper or another format ? -
I'll try it ..
The CUDA tool is by NVIDIA, and came direct from their web site. They know a thing or 2 about video, so pretty sure it will not be malicious. -

OK ... some things found during testing.
Task was to find a way to get Panasonic VRO files onto a USB stick to allow them to be played on SMART TV
# Found mpg files would play direct on TV - so no need to convert to MKV
# Maybe no need to use DVDVob2mpg .... simply changing .vro to .mpg seems to have exactly same effect (as far as I can see) Mediainfo shows exactly same resultant file structure.
# mpg to MKV was tried (nice interface on MKVToolNix) ... and MKV files almost the same size at original mpg (not 2.5 times as previously)
When I tested I found that the original .VRO files will also play direct anyway .... so I don't have to convert at all - ... lightbulb moment
Anybody know a way to join VRO files together ? ......... if not I will continue and use DVDVob2mpg but not convert to MKV
So original request taken an alternate direction - but for me interesting items learnt. -
Don't think you can join vro natively as vro.
Simply renaming to mpg can work but since the vro is a container it can store more than one recording. So you can get a bit of one and another in the same vro.
Vegas can join those but if the recordings are not exactly the same bitrate etc it could well re-encode.
It was not my intention to scare you but there is often a payload attached to a 'free' program. And there was no indication of the source in your earlier post.
