did you create the image as "supervcd" or as "svcd"? (it can be set afaik
in the preferences somewhere, default is "supersvcd", which seems to be
some pre-IEC spec)

well, vcdimager tries to adhere to the IEC62107 SVCD specification,
iauthor does create by default some pre IEC svcd image... which many
players may regard as the actual standard... are there any firmware
upgrades available for your player?

I guess philips players show the correct information... is there anyone to
confirm this?
