 The PS3 only recognizes the FAT filesystem on usb drives. No NTFS or any
Linux filesystem. That might be the problem there.

 It's very important to know what *exactly* the format of the original files
is. Ideally the console output from mplayer when playing the files will tell
us (the lines starting with "VIDEO:" and "AUDIO:"), but if that's not easily
available can you at least run the command 'file' on the originals? For
example, when I run 'file' on some media files I have handy, it says:

$file *
GetYourOwn.avi:  RIFF (little-endian) data, AVI, 320 x 214, ~30 fps, video: DivX 4, audio: MPEG-1 Layer 3 (stereo, 44100 Hz)
GetYourOwn.mpg:  MPEG sequence, v2, program multiplex
GetYourOwn2.mpg: RIFF (little-endian) data, AVI, 320 x 214, ~30 fps, video:, audio: MPEG-1 Layer 3 (stereo, 44100 Hz)

Running mplayer on the first one yields (with a little cruft removed):
$mplayer GetYourOwn.avi
VIDEO:  [divx]  320x214  24bpp  29.970 fps  213.6 kbps (26.1 kbyte/s)
AUDIO: 44100 Hz, 2 ch, s16le, 64.0 kbit/4.54% (ratio: 8000->176400)

Here is a script I use to convert random video files (usually *.flv files
from YouTube) to media files I can play elsewhere, including the PS3. Note
that although it's titled 'flv2avi', the format of the input file(s) doesn't
matter as long as mplayer can play them.

----- flv2avi.sh -----
#!/bin/sh

# Converts FLVs to AVI files suitable for viewing outside of web browsers.
# Run as 'flv2avi.sh [new file name] [list of one or more movie files]

# If you're skipping frames, increase FPS. If duplicating, decrease FPS.
# Usual values are 24000/1001 (23.976), 24, 25 (PAL), 30000/1001 (29.97), 30.
#OFPS=24000/1001
#OFPS="-ofps 30000/1001"
OFPS="-ofps 30"

# If mencoder misdentifes the FPS of the input file, set it here.
#IFPS="-fps 30000/1001"
#IFPS="-fps 30"

# If your system has more than one cpu/core, multithreading may help. Set this
# value to the number of cores you have available.
#THREADS=":threads=2"

# Set audio mode - these are arranged in decreasing order of likelyhood
# to sync properly
# Most FLVs already have MP3 audio, no need to mess with it.
AUDIO=copy
# Constant bit rate MP3, the 'br' field sets the bit rate
#AUDIO="mp3lame -lameopts cbr:br=128"
# Average bit rate MP3, the 'br' field sets the bit rate
#AUDIO="mp3lame -lameopts abr:br=128"
# Variable bit rate MP3, sometimes has sync problems
#AUDIO="mp3lame -lameopts vbr=3"

# Set crop, if needed
# Get these numbers by running the command: mplayer -ss 60 -vf scale=320:-2,cropdetect [file]
#CROP=",crop=320:160:0:28"

# For mixed progressive/telecined content
#PULLUP=",pullup,softskip"

# Set video bit rate, feel free to experiment here to see what fits
#VBITRATE=224
#VBITRATE=336
#VBITRATE=448
#VBITRATE=512
VBITRATE=1024

# Use DIVX
DIVX="-ffourcc divx"

# These are the key parameters we gotta have from the user.
# Spaces in the output file name are probably not a good idea.
NEWNAME=$1.avi
shift
MOVIE=$*

# Just in case one's left over from a previous encoding run.
rm -rf divx2pass.log

# Two-pass encoding, takes longer but produces best quality for a given bitrate
mencoder ${MOVIE} ${IFPS} -ovc lavc -lavcopts vcodec=mpeg4:vpass=1:turbo:vbitrate=${VBITRATE}${THREADS} ${OFPS} ${DIVX} -oac ${AUDIO} -af volnorm -o /dev/null
