to troubleshoot and replace a bad SATA power connector

disc mount issues and delay, before the burner device
worked properly again.<br>

So far I have tested successful burning on BD50-RE DL
discs with K3b/cdrecord using a single 2GB HDV clip
with PCM transcoded audio written to Blu-ray video UDF
image. For HDV this time I've tested BD-RE discs from
two manufacturers, Verbatim and unlabeled (dealer
Slowmoose). Last year I tested also SD-Bluray video
successful burned on TDK BD-RE discs.<br>
</font> <font face="Courier New, Courier, monospace"><br>
</font> <font face="Courier New, Courier, monospace"><br>
And most important, the discs starts as autoplay after
loading in my Samsung UBD-K8500 Blu-ray hardware
player. The quality of interlaced video and PCM audio
seems for me equivalent via VLC and Samsung BD player.
Testing is executed on VLC/Leap 15.4 workstation and
Samsung BD-player, both connected to the same Asus 27"
LCD monitor (PB2780Q), easy switchable via DP and HDMI
ports respectively.<br>

To summarize and repeat procedure for this test case:<br>
</font> <font face="Courier New, Courier, monospace"><br>

A question before leaving some error/warning details
from various tools output/log below:<br>
</font> <font face="Courier New, Courier, monospace"><br>
Is it possible to get bdwrite to keep the original,
multiple video clip names? In this case single clip:
hdv01.mts<br>

think only way I saw in manual (but not tested) is to add

Yes, there is something to explore. The manual sample screen seems
to be selectable human info titles that points to the clips.<br>
<br>
To be sure we talk about the same thing, I will detail this sample
case a bit.<br>

12 directories, 9 files<br>
<br>
<br>
The last line contains the video itself with file name
'00000.m2ts'<br>
This corresponds to my single video clip
'hdv01_m2t_pcm_bluray.mts' from <br>
bdwrite /mnt/test hdv01_m2t_pcm_bluray.mts<br>
<br>
HDV and also DV (SD) requires ca 13 GB disc space pr hour (from a
recorded 60 minutes tape). That is a 46 GB BD50-DL optical disc
have space for about 3.5 hours HDV or DV video.<br>
<br>
When HDV.m2t or DV (digitized from Hi8 analog tapes) are
transfered to the Datavideo DN-300 disk recorder, the video is
auto splitted in 2,0 GB named clips. A sample of DV clips and
naming from two Hi8 tapes archived on optical BD data discs:<br>
<br>
/video/DV> du -h dv01* dv02*<br>
2,0G dv01.dv<br>
2,0G dv01_01.dv<br>
2,0G dv01_02.dv<br>
2,0G dv01_03.dv<br>
2,0G dv01_04.dv<br>
2,0G dv01_05.dv<br>
2,0G dv01_06.dv<br>
389M dv01_07.dv<br>
<br>
2,0G dv02.dv<br>
2,0G dv02_01.dv<br>
2,0G dv02_02.dv<br>
2,0G dv02_03.dv<br>
2,0G dv02_04.dv<br>
2,0G dv02_05.dv<br>
505M dv02_06.dv<br>
<br>
It is these clip names it would be practical (due to archive
register) to keep also on the playbackable, source Blu-ray video
discs?<br>
Beside additional clip info/titles could be useful.<br>

<font face="Courier New, Courier, monospace">The very first
procedure line above had a minor syntax typo in the input file:<br>
> ffmpeg -i hdv01.m2t -c:v copy -c:a pcm_bluray
-mpegts_m2ts_mode 1 hdv01_m2t_pcm_bluray.mts<br>
<br>
It should be noted that ffmpeg-5 with pcm_bluray encoder is
required here (therefore I used Tumbleweed just for this)<br>
<br>
<br>
Else I suggest that the # comments in the manual should be kept to
explain what happends.<br>
And also how the mkudffs size was calculated.<br>
