.... You cannot transfer files to them....
Some can, but generally you can only play the files if they are in the PVR's own format.
By the way, just because a file is an AVI does not guarantee the codec is playable (even on a PC). You can put content with many different codecs inside an AVI file.
AVIs would rarely be high enough quality that it
needed a PVR to play it, so something like that Aldi might be a good option.
