If you buy one of these, plan on having to update the firmware for
the DVD rom drive (this is not the same as the firmware for the
player itself). A LOT of the DVD rom drives included in these decks
are buggy and will skip/freeze constantly.
This
link gives info on updating the drive firmware.
Note that upgrading the drive firmware may require taking the drive
out of the DVD player and connecting it to your PC. If you are not
comfortable with this prospect, I would think twice and three times
about whether you want to buy this deck, even for $50.
