standalone dvd players: is there a file restriction view limit?

[mike69]

I have a philips dvp5992 and I just noticed this recently when adding a bunch of new files to my external 1gb hd (fat32) to connect via usb to the dvd player. Usually, when you power everything up, it takes some time to scan for all the files, but eventually after about a minute, it loads everything up and all the content is there. Recently, I filled it about halfway and loaded it up and while I was checking some random folders to view some movies, some of them didn't display as if it was hidden from view. I thought that it was because it was an empty folder and I had deleted the files contained in them, but I disconnected the external and brought it up to my pc and found that the folders and files are there, but I don't know why they weren't showing up on the dvd player through the usb scanner. It ends up being the same files and folders so it has me wondering if there's a viewer limit on that machine when it comes to how many files or folders it can hold in memory for display. I'm currently having it connected to my pc to scan for any errors that there might be. I can't figure out if there's something about these machines that wasn't included in the manuals that I should know, limitations or restrictions or whatever.

I didn't know where this thread should belong so if it needs to go somewhere else, please move it.

Philips players have a limit of 648 files and 300 folders,it also has problems with drives over 500GB:

From the manual:


Helpful Hints:
– The USB jack does not support the connection of other USB devices except to a USB flash drive.
– The unit can only support up to a maximum of 300 folders and 648 files.
– When the USB device does not fit into the USB jack, a USB extension cable (not supplied) is required.
– Copy-protected files are not playable.


You beat me to it MOVIEGEEK

when you say maximum of 300 folders and 648 files, which is of higher importance? the number of folders or the files contained per folder? are you saying each folder can have up to 648 files? what about subfolders? how would that work?

Since we didn't write the firmware it's impossible for us to say "which is of higher importance", but I would not conclude that if you exceed one and stay below the other it's OK. I'm sure that folders includes subfolders, so you can't "trick" the player by having 299 folders in the main directory and putting subfolders underneath that. I'm sure that 648 means total number of files on the disk, wherever they are.

The 648 file limit is per folder. You could, for example, have 10 folders each with 300 files and still be OK.

oh i see. Yeah, I just checked the properties and found out I had about 400 folders counted. Surprisingly, I only added maybe a dozen folders recently before I noticed this happening so I don't know since the specs mentioned were about max of 300 folders why it all of a sudden started to happen.

Once you go over the limit, is there any way to tell what the viewer will start to not read? Is it by the most recent entries that it becomes invisible to the standalone dvd player or just some random thing?

Also, I see the a thread around in this forum on a new customized firmware for this unit that's been written. Does the newer firmware allow a higher capacity of what's read in terms of going beyond that 300 folder mark?

Are you sure that the 648 file limit is per folder? I would think (based on not much knowledge at all) that the file limit is based on some amount of internal memory (64mb??) and the length of the file name. the files would be held in some sort of table in memory and that would be referenced by a two byte pointer giving 640000 possible memory locations with 11 bytes per filename....???
If the limit was per folder that would mean a limit of 194,400 files! surely too much..what modified firmwares do to this equation is surely left to the imagination...

possibly your files have the wrong file extension??

The "300 folders" and "648 files per folder" limit may not mean that you can fill all 300 folders with 648 files. There may be an upper limit on the total number of files too. But from what I've read the total number of files limit is definitely more than 648.
