Page 1 of Dantheman, HELP!

Dan, or anyone else who may be able to help:
I posted a query on the software forums just after Christmas about why Fawlty Towers would not play on my Cyberhome ADN-212 player but works OK on my PC DVD drive under Power DVD software.
Dan said he might be able to help but I assume he`s either not able to after all, or been too busy.
Anyone else know why this should be and whether it`s a hardware or software problem and if there`s any way to fix it.
I thank you in advance for your assistance gentlemen.
