Issues playing MP3-c files on a DVD player?

I have this collection of about 50 MP3-cs saved on my computer, which I recently burned onto a DVD for my sister
She’s using a certain DVD player, but whenever she tries to listen to them, it only plays the first four tracks before throwing some kind of error message for everything else
It actually happened last year too—when she tried listening to other MP3-cs I had burned onto a DVD for her, she ran into the exact same issue where she couldn't play the full set
I suppose it's hard to pinpoint exactly why this keeps happening
Does anyone here happen to know what the underlying problem might be?
What steps should I take so she can finally enjoy all the songs without any trouble?

Have you tried running them through a different player? And are you absolutely certain those tracks are actually MP3s and not something else, like AAC or WMA...

They’re all actually MP3 files—I used that "Free YouTube download" program and just made sure to select the "download to MP3" option before starting the process.

I usually burn my discs using Nero, typically setting the speed to about 12x or 16x—I think it’s the track-at-once mode
It honestly stresses me out a bit because every single time I burn a batch of songs for my sister (who lives out on the coast), I find myself worrying whether the whole thing will actually play smoothly or if she'll just end up with a partial, glitchy mess.
I can't quite wrap my head around what's causing the issue—I'm wondering if the problem lies with the MP3-ac files themselves or if it might be how Nero is handling the burn process.
The weird thing is, all those MP3-ac files play perfectly fine without any hiccups when I listen to them on my computer.
Does anyone happen to know of a fix for this kind of situation?

Is there any chance that DVD player has a USB port? It would be so much easier if I could just move my songs onto a USB stick LP.

🤦
Nobody needs to lecture anyone else, especially when you claim to be burning at 12x to 16x speeds on a DVD.
I suppose since your parents haven't taught you better, I have to.
DVD 1x write speed is already nine times faster than a CD. It’s massive. The industry claims these high speeds work, but they aren't reliable.
In raw numbers, 1x on a DVD means 1.4 MB of data per second. Do you actually realize what that implies?
The laser has to pulse incredibly bright against the DVD 1.5 million times per second.
It is technically possible, but it's an extreme speed. You're pushing the hardware too hard.
If you burn at 12x, for example... 12x multiplied by 1.385MB is exactly 16MB per second.
How can that be stable? The laser overheats and weakens, which you clearly didn't consider. It's different from magnetizing a Hard drive, where there are specific limits. Still, magnetizing metal is much faster than optical burning.

Bottom line: burn at a lower speed (1x-4x) to ensure the CD or DVD actually works. If my sister's player still can't play your tracks after that, it means her laser is either dusty, worn out, or just imprecise.

Or, as Larry Ortiz5 suggested, just use a USB stick.

So, I was thinking—one potential culprit here could actually be the burning speed itself.
Maybe try using Nero and setting the burn rate to the absolute lowest possible setting (for me, that’s usually around 2.4)
Does anyone happen to know if there's a better burner out there than Nero? Based on some of the feedback I've seen online, I was under the impression that it was pretty much the gold standard for this kind of thing.

Nero is definitely more on the commercial side of things, but honestly, you can just use CdburnerXp for free. In my experience, it gets the job done perfectly fine, even though I haven't actually burned anything in months. It’s possible your burner might be acting up, too. I remember back in middle school, I had an old CD-ROM drive and eventually upgraded to a burner, but the songs I made kept skipping. I didn't realize until later that the actual CD-ROM drive was the culprit—it wasn't reading properly, so it ended up burning everything onto the disc incorrectly. Once I swapped it out for a newer, better DVD drive, all the tracks I burned came out sounding great. Back then, we used to burn things by reading from one disc and writing to another at the exact same time. I think back in those days, operating systems weren't really capable of creating a temporary image of the media to burn to a second disc later on.

My sister actually owns a Pioneer DV 2242 —it’s right here
From what I can tell, this model features a USB port
Do you think everything would play smoothly if I just loaded it onto a USB stick instead of burning it all onto a DVD?

Oh man, why would you even bother with burning DVDs? It's such a hassle. You can just copy and paste your downloaded songs onto a USB stick, plug it into the player, and you're good to go—it should work just fine. Honestly, it’s so much faster and more efficient than messing around with CDs these days. It supports MP3 and WMA files anyway.

You're absolutely right—that's exactly how I plan to handle it, too.
