Re: Running SDFtool Flasher on a Mac (Sonoma)




See guides Mac commands below


I'm sorry, but I'm not following your reply... I have a drive I want to flash, but don't have a Windows computer - I have a Mac, and a Linux box.

Thanks,

Re: SDFtool Flasher

Hello,

This question may have already been answered - but I couldn't find it! Is there a version of the SDF tool that runs on macOS (Sequoia)??

If not - are there any recommendations for a firmware upgrade for my BRXL-16U3 (Buffalo)?

FWIW: This is a fairly recent model, bought new in 2025 ...

Re: Does makemkv use H264 to encode BD video by default?



And that seems to be the answer! MakeMKV does in fact use the "High" profile, defined in the Wikipedia article as follows:

High Profile (HiP, 100)
The primary profile for broadcast and disc storage applications, particularly for
high-definition television applications (for example, this is ...

Re: Hard Drive Prices

Before getting carried away with H.265 as a way to save disk space, perhaps you should consider the topic of Generation Loss .

The problem is this: Your source data (BD/DVD) contains video data that has already been encoded/compressed using a lossy codec; i.e. mpeg2 with DVDs, H.264, Hi Profile ...

Re: Does makemkv use H264 to encode BD video by default?



... encoded with H264-BluRay - a variant on H264.


Incorrect, there's only different profiles/presets. ffprobe might be displaying a slightly more acute description if you've supplied a .m2ts or something like that.

Does makemkv use H264 to encode BD video by default?

I'm trying to confirm some "notions" that I've come by - without being able to recall exactly where I got them. I'd appreciate any comments or feedback:

Notion #1: The video on DVDs is typically encoded with the MP2 codec.

Notion #2: The video on BDs is typically encoded with H264-BluRay - a ...

Re: Using 'ddrescue' with MakeMKV to process defective DVDs


This is in the manual for ddrescue, although the manual does have problems with vagueness in the early sections describing what exactly happens in the various phases. Check the sections about optical disc recovery, and some of the examples involving multiple discs and multiple drives.

I do ...

Re: Using 'ddrescue' with MakeMKV to process defective DVDs


The ddrescue map file allows you to interrupt the operation and resume it some other time -- with a different disc (same pressing, different copy), different computer, different optical drive, etc. Also, you can resume and tweak the operation if you decide to reverse direction, or change which ...

Re: Using 'ddrescue' with MakeMKV to process defective DVDs


Do the various ddrescue phases, one at a time, alternating between drives. Whatever is skipped by the first drive can be attempted by the second drive, which may be able to read problematic areas better. That is better than just using a single drive and having it get bogged down on difficult areas ...

Re: Using 'ddrescue' with MakeMKV to process defective DVDs


You should use multiple optical drives at the various ddrescue phases, certainly before the time-consuming scrape and retry phases.


Sorry, but I'm not following your suggestion... I've got 2 drives, but it completely escapes me as to how I'd use them both to recover an ISO file from a "failing ...

Re: Can MakeMKV process a "rescued" DVD / ISO file(s)??

It seems it can! Use the 'File' menu to open the ISO file (created via GNU's 'ddrescue' utility), and process it "as usual" using MakeMKV.

A few notes to summarize my experience using 'ddrescue' with MakeMKV:

1. It's not clear to me exactly what causes a DVD to malfunction such that MakeMKV will ...

Using 'ddrescue' with MakeMKV to process defective DVDs

I'm finding more DVDs in my collection that are un-readable... un-readable not only by MakeMKV, but also un-readable even in my "TV-connected DVD player". Searching for a solution has turned up a GNU package called 'ddrescue' . I've used 'ddrescue' to create an ISO file of a DVD, and it seems the ...

Question re License terms

I'm considering buying a license for MakeMKV. However, I've been unable to find any document or documentation that describes the license terms.

Does anyone know where the license terms for MakeMKV can be found??

Thnx,
