A Pioneer 4750 mp3 playing query

tsk1979 · 12th December 2006, 16:29

Greetings folks. I have 2 teeny weeny queries about mp3 playing capabilities of 4750.
1.
Nowadays the ID3 tags of mp3 files have evolved with many mp3's in itunes having the capability of "logo/poster" embedded in the mp3 file itself. So when you play that file, the artwork shows up.
I am wondering wether mp3's with such complex ID3 tags will play in the 4750. I am not planning to see album/song artwork, since its a low end mp3 player, my only worry is whether the player will recognize such a mp3 file

2. Directories
When I have a mp3 CD, it can have multiple directories. Is there a limit on the number of directories. Any limits on nesting. For example 100 directories and in each directory 5 more directories? It may take a longer time to load mp3 CD if lots of directories are there, but will it load the entire CD or there is a number of directories cutoff limit?

ID3 tags are backward compatible so your HU will read that part of the ID3 tag that it is degined to read the rest will not be read.

some HUs have a limit of 255 directories/folders. I am not sure if there is atheoretical limit to the number of folders one can have or how "deep" the nesting can be.

Yep tanveer there is a limit on the amound of nesting you can do for directories. I'm not sure till how deep. Some mp3's need it to be in the root directory else cannot access.

I have a 5750 and it can access upto 5 directories depth. I havent tried more than that.

Max Directory = 8 --> This is the max depth you can go...
Max Folder = 99 --> this is max no. of folders per folder.
Max file per disc = 999--> this is the total no of files per disc, in all the folders...

This no. is usually limited by the hardware capability of the HU... (remember, going into each folder means pushing the info into the stack..)....

dont know if everyone faces this problem...but too many mp3s on one CD and the player tends to skip a lot while reading the last few tracks. i have a pio HU & i make it a point not to burn around 50-60 tracks on a CD. also, theres no point in running folders 'deeper' than 3 clicks down IMHO.

tsk1979 · 13th December 2006, 11:21

But whats the point of having a mp3 player if you cannot burn more than 50 tracks?
I think 999 is the limit, and most of my CDs(Totally flat ones) have around 130-140 tracks.
The only time I faced a problem with some tracks not playing was when I burned through itunes and because of the way it burns CDs it put them album wise in different folders, and this resulted in around 105 folders and some tracks did not play at all.

Thanks for all the tips people

I have MP3 collections on a CD, running to around 150-160 songs per CD. and they all play without any problems...
This is what I usually do...
1. Get CD and rip them using Windows Media Player. This would create folders based on Artist Name and Album name (the default setting)...
2. Put them all into one single location.... Mix and match albums to get a size around 700 MB.
3. Burn the files to a CD using Roxio or some other CD Burning software!....

Are CDs still cheaper $ per Mbyte. I thought hard disks esp the 2.5" types (the 3.5" HD are not shock resistant enough) are now cheaper. With 80GB on a 1.8" hard disk (expect this to slowly rise to 200Gb on a 1.8" disk by 2008-9) you might not needs CDs anymore.

navin, with prices of 80GB(2.5 inch) ~ $200, CD are still cheaper per Mbyte.
10 CDs would cost you Rs 100 ~= 6.5 GB. so for less than Rs 1500, you are already having >80GB of storage.... only disadvantage, the clutter of 150 odd CDs lying around....

Go thru this post....
http://www.team-bhp.com/forum/car-en...a-said-he.html

also... few of these harddisks come with USB connectivity!.. But I am not sure whether, USB enabled HU would read the contents and play.... also you might need to power the HDD thru an external source....

abhibh · 13th December 2006, 17:02

Yeah that is what i want to know coz i am buying a portable 2 inch laptop hdd and it will be good if that can be used with AUX in easily.

hydrashok · 13th December 2006, 17:36

abhibh, the really small ones that don't need external power should work (theoretically). Nobody here has tried it yet. I tried my 2GB Kingston with a Blau Memphis a few days back (at the showroom, just for kicks heh, heh), and it worked perfectly. I'd filled the Kingston to the brim for testing.

Sorry old man - a CD can store 0.75Gb for 10 or 12 rupees. Thats about Rs.0.01333 per Mbyte

A portable 80 gb HDD is about 5000/- that about 0.0625 per MB. CDs are cheaper.

In comparison, don't DVDs kick ***? 4GB for 20 bucks? I dont know anything cheaper than that. But BD-R is sure to cream DVDs sooner or later.
