Dear DeVeDe users and gurus, would you mind sharing your secret knowledge, please?

The problem I am solving is to create disks with films for viewing them on some cheap SONY DVD player (DVP-SR370 if anyone cares). The owner of the player neither owns nor knows computer due to age. Source films are taken from elsewhere in different formats (MKV, M2TS etc) of size much bigger than the 4.7GB DVD disk. The player understands VideoCDs, VideoDVDs and (it's manual states that) it also supports MPEG/MP4 files if written on data DVD with UDF filesystem. No MKV, no other formats.

I made a few VideoDVDs, hit "adjust disk usage", DeVeDe showed "99%" and it worked, the player happily plays the film from the disk. But I noticed that only about 3.1GB is used for actual video files (.VOB-s) in this case, so video quality degradation is pretty significant. So less than 3/4 of the disk space is actually utilized.

"Why not use more space for video, with better disk space utilization", I thought. If I take a 20GB M2TS file and convert it to 4.6GB MPEG, it should have better quality compared to 3.1GB if DVD. Is it a reasonable assumption, isn't it? 4.6GB of video information should retain more image quality than 3.1GB.

Okay, I started the "DivX / MPEG4" project, added one large M2TS 1920x1080p file there, selected "4.7GB DVD" for media and hit "adjust". "99%" it said to me.

99% share of 4.7GB should be 4.653GB, or 4.6GB at least, correct? But after conversion, I got the movie_0.mpg file which is 3.6GB size only. Why???

I tried converting a few other video files of about 6-10GB sizes (MKV) to "DivX / MPEG4" and the result is the same - DeVeDe 4.8.0 instantly offers me only 3.6GB file for 99% of the 4.7GB DVD disk, what's wrong with my math???

How do I tell DeVeDe to create full 4.6GB video files for my 4.7GB DVD+R disks?

Thanks in advance! Regards, Andreas

Same here at H264 (i think) and the new H265/HEVC converting option, it stabbing at 3,8 GB, this really sucks. want to use the full disc size of 4.38 GB.

The new HEVC option works great, but even at this codec want the best qaulity for the best possible size. Not a lower size and qaulity that does'n fit the max disc size.
