Verbatim DVD+R DL maximum movie minutes/quality loss?

[blackholesun85]

Hey there I'm new to the forum and looking to burn a few downloaded movies which are out of print onto a Verbatim DVD+R DL disc which claims to have a maximum capacity of 8.5 GB and 240 minutes.

Does anyone know what will happen if I try to fit say three or four films onto one disc but the total VOB size is still less than 8.5GB but the total minutes exceed 240 and totals around 300mins?

I normally convert the mp4 or mkv files to VOB using winxdvd author and then create the menu using dvdstyler and burn using imgburn. It seems like dvdstyler will allow me to create the dvd as long as the VOB files combined are below 8.5GB but doesn't seem to care about exceeding 240 minutes!

Does anyone know if there will a major loss of picture or sound quality if I burn these to a disc?

Any help would be appreciated from anyone thats attempted to do this themselves in the past. Thanks!

Nothing will happen, it works fine. 240 minutes is just a recommendation for a good balance between quality and play time. Same with 120 minutes for single layer discs.

Of course 300 minutes means the average bitrate will be lower and therefore the video quality might be slightly compromised.

Ive seen some burner programs allow to select "overburn", which allow for exceeding the disc limits, it work sometimes and sometimes it does not! The entire disc can be "consumed" and not work at all if it exceed the limit to much, it seem allso like it perform different for various type of videos/data files, as one disc was able to go pretty far over the limits while the other stopped function and the exceeded limit was just an small difference!

Ok thank you so if I download say three or four film mkv or mp4 files and convert each film to a vob file and import each vob into dvdstyler to create the menu and dvd will dvdstyler automatically lower the bitrate and picture quality if i exceed 240 minutes or will the quality be the same as the original converted vob files when burned to disc?

If the total size of all converted films combined does not exceed a maximum of 8152 MiB ("8.5 GB"), there won't be an additional quality loss. Of course the conversion to not-exactly-high-bitrate MPEG2 itself is lossy.
