See below e-mail exchange I had with AticoUSA the company that distributes T.D.E. products
It seems as if they will send me a new remote to replace my broken one so maybe they will sell you a new one to replace your lost remote.

Thank you for your recent correspondence regarding your Personal DVD player.  Unfortunately because of the advanced features of your DVD's a remote would be required to play them.  A replacement remote is available for replacement.
 
Please mail in the faulty remote along with a copy of this email as well as your name, telephone number mailing address to:
 
Atico International
Attn:  Luis Lopez
501 South Andrews Ave
Fort Lauderdale FL 33301
 
Once the non-working remote is received a replacement will be mailed out to you within 2-4 weeks.
 
Thank you
 
Luis Lopez

Message=The remote for my T.D.E Systems 7 inch portable DVD player model # 325721 is no longer working (changed battery and still nothing); it seems that without the remote almost all my DVDs will not go past the root menu even if I press play on the unit itself.  Can you tell the trick to get the player to work without a remote or how I can buy one?
