Coby TF-DVD7377 7-Inch DivX Compatible Portable DVD Player
I am still experimenting with the player. It handles .avi files well - I have many older movies (Public Domain)and new ones. It did not play .mp4 files, and sometimes if I go fast forward and then play the sound stops in older movies. It can handle SDHC - secure digital high capacity cards. I tried a 16 GB card and it plays the movies fine. I did have to get a newer card reader that I installed on my desktop computer - regular SD goes up to 2 GB, I believe. I tried to plug in a set of USB speakers but no sound came out, but there was no discussion that it would work in the specs. I tried a few USB thumb drives and they play fine, and also an external hard drive in a USB case. The player has a button to push for the type of media - it lists DISC, USB, and CARD options, and you can select one at a time. As with my older player, the sound in some movies is not loud enough. However, there is a big range of sound levels in different movies. 
(I have severe background noise where I use the player, so sometimes I use headphones or external speakers.) So I give it a thumbs up overall. I will just try to adjust my selection process - some sites give a choice of different formats and I will get the .avi files now if available. It does play the standard movie format VIDEO_TS usually found in rentals or purchased movies. 

Issue 1) It automatically starts playing the first movie on the media - but I want to choose - I may have already seen it, or I want a shorter length movie due to my time limits,... I have to hit STOP on the remote to see the list of movies. 
Issue 2) In the Setup menu, Misc - if the screen saver was ON, and I paused the movie, it seemed to mess up resuming it when I got back. I turned it OFF. 
Issue 3) I have a Disc Resume option (ON/OFF) in Setup/Misc which is not shown in the manual. I did not see what that does so far. 
Issue 4) Setup option for Audio Setup - Digital Out - RAW or PCM --- I didn't know what PCM stood for - it is pulse code modulation, preferred for DVD's. 
So a general comment would be that a few extra lines of explanation might be really nice in some places. 
I will try other formats, like .flv, .mpg, .mov and so on but it was stated as "DivX" compatible, and so far it does that OK. 
Note - this was listed as model 7377 on the Amazon site but I actually have 7379.
