Disc burning question
Hello all,
I burnt some home movies to a bd r with cdburnerxp which said all the files were burnt to disc correctly. But when I test the disc in my and my fathers blu ray players a message come up saying "unknown disc". I tested both players with another bd r from the same tub that I burnt last year. Both player recognise this disc. So I then split the home movies as to fit on a dvd r. Same error on both players. Both players play cdr, dvdr and bdr that I burnt last year and still both play blu ray movies that I bought. Why is this happening? |

Burners can play content that hasn't been closed but stand-alone players usually won't. That is, you need to "finalize" the disc, so the burn session gets closed. https://cdburnerxp.se/help/references/burnoptions Burn Method DAO or Finalize options Wolk already mentioned the encoding format. You have to review the manual for your players to see which they support, and make sure that's what you burnt onto the disc. Disc burners and players rely on mechanical alignment. If a disc drive is sufficiently misaligned, you can play the content using that disc drive but not with other disc drives. A dirty lens can emulate misalignment. You might be able to reach through the front/loading slot with a long-stemmed ear swab (cotton swab on a long wood stick) with some isopropyl on the cotton swab to clean the lens. Since you're coming in at a right-angle through the slot to get at the LED head, you may have to tease the cotton swab to swell it up to get it to rub against the lens. There are discs with itty bitty bristle tips embedded it for trying to clean the lens. Those are rather a hit-and-miss method of cleaning the lens; for example: https://i.ytimg.com/vi/WVHBRMQieMU/maxresdefault.jpg https://upload.wikimedia.org/wikiped...ns_Cleaner.jpg |

Both player can play this format - I have tested older recordings and they work. I have a blu ray laser cleaning disc I bought many years ago which uses tiny brushes. I will try this and get back to newsgroup. Thanks to all in advance. |

Check your player, and make certain it can recognise the format. If you don't know what the format is, go to the Control Panel, find Folder Options, and untick "Hide known extensions". Good luck. I forgot to mention, in cdburnerxp, I chose to close the disc recording. |

You need to take a closer look at the file format. Container and codec. If nothing else works, ffprobe from the ffmpeg package can tell you about the content. Click the selector bars, then click Download Build. I've had trouble with some of the newer stuff, so there's no guarantee that even the release stream 4.0.2 will work. Some libraries got added to the main release, that don't seem to have matching Win32 DLLs to cover the Windows builds. But, you can test and see how well it works this week. https://ffmpeg.zeranoe.com/builds/ Paul |

I use a program that is a front-end to ffmpeg. For example, VideoLan's VLC. When I play a video file, I can use its Tools - Codec Information menu to see what was used to encode the contents inside the container file. For example, I just played an .mp4 file and it had: stream 0 (video) codec: H264 - MPEG-4 AVC (part 10)(avc1) stream 2 (audio) codec: MPEG AAC Audio (mp4a) I played an .avi file (no audio) in VLC and its codec info was: stream 0 codec: Microsoft RLE Video For an .mp3 file (obviously just audio): stream 0 codec: MPEG Audio Layer 1/2 (mpga) All my .mp4 files (that I looked at) all use the same coder. That's probably due to the video being captured from the Web using the same stream capture program (Applian Replay Media Catcher). I don't have many media files and download few directly from a site. The only MP4 codings that I can think of are MPEG-4 AVC (aka MPEG-4 part 10 or H.264) and MPEG-4 part 2. Those are different formats, so your player saying MPEG-4 capability isn't telling you which format it supports. https://en.wikipedia.org/wiki/MPEG-4_Part_2 "Note that MPEG-4 Part 10 defines a different format from MPEG-4 Part 2 and should not be confused with it. MPEG-4 Part 10 is commonly referred to as H.264 or AVC, ..." and "MPEG-4 Part 2 is H.263 compatible in the sense that a basic H.263 bitstream is correctly decoded by an MPEG-4 Video decoder." H.263 is an older spec than H.264 but both were published (although perhaps not widely adopted) about the same time (1996 and 2003, respectively). BD players started showing up in 2003 (but were very pricey at $3000+). Once you find the coder used for the source video that you are burning onto BDs, and after using VLC or some other video player that tells you the codecs used in a video, check the specs on your father's BD player to see if the same codecs (video and audio) are supported. If the BD player just says MPEG-4 then check if it also lists H.263 and H.264. BD discs come in a variety of flavors: 25GB single-layer, 50GB dual-layer, 100/200/300GB (BDXL). They can also be encoded using CLV or CAV. Since you've given no details on brand and model of your BD burner and you and your father's BD players, no idea what they support. Is the BD burner drive in your computer, or are you using someone else's BD burner drive on their computer? From your original message, you and your father have BD players but there is a hint that you used someone else's BD burner. If you are using someone else's BD burner drive, is it the same one now that they had last time (for the BD-R discs that still work in your players)? If the computer with the BD burner drive is your computer, and if all you are doing is copying (burning) video files onto an optical disc, have you tried the in-built burner in Windows 7? Instead of super-huge video files that require a BD disc or spanning multiple DVD or CD discs, get a video that will fit onto a DVD or CD disc (whichever you have that are write-once or writable) and see if using Windows 7's own burner (which only supports CD or DVD, not BD) lets you create a disc that is playable in your and your father's players. See: https://helpdeskgeek.com/how-to/burn...indows-7-8-10/ You said in another subthread that you "closed the disc". Does that mean you use the DAO (Disc At Once) burning methond *and* enabled the Finalize Disc options? https://cdburnerxp.se/help/References/burnoptions |
