E-Gadgets help.
I got this file-mate HERE from walley.
Now not sure if this DVD player might not be more inline of what I need, want.
SONY DVP-FX970 9" Portable DVD Player. Most of what the tablet can do, could be done on phone. I’d like to download math lessons from Kan’s academy. Which I would have to reformat to use on either one, so I could either download to tablet or burn to DVD.

The tablet battery time sucks. The dvd not sure if I can stick a bunch of lessons on 1 dvd.
Below from Sony.

• The player may not play a combination of two
or more video files.
• The player cannot play a video file of size
more than 720 (width) × 576 (height)/2 GB.
• The player may not play certain video files that
are longer than 3 hours.
• Depending on the video file, normal playback
may not be possible. The picture may be
unclear, playback may not appear smooth, the
sound may skip, etc. You are recommended to
create the file at a lower bit rate. If the sound is
still noisy, check the audio format. (MPEG-4
video files should be AAC LC.) Note,
however, the player does not conform to
WMA (Windows Media Audio) format.

No reviews at newegg, only the best at Sony. Can ya believe that? After looking at the manual, not sure if it does any flappin thing.
Any thoughts on this fluster cluck? BTW I would need earbuds or something for the dvd thingy. Some crap came w/tablet.
Thank you nice folks in advance.
