I friend was recently bragging about how he plays his kids home movies on his T/X on long business flights. Personally, I’ve never tried it, but it sounds interesting.
Q: Is there a specific program (hopefully shareware) that might allow home movies dropped onto an SD card to play on a normal PALM T/X?
I’ll second TCPMP - it’s a great bit of freeware. You might want to use something like VirtualDubMod to resize your video down to the display resolution, to save space on the card. http://virtualdubmod.sourceforge.net/
