I think you guys are right:
well i found out that the combi drive is an old dvd-rom and that it is most
likely that old drives won't read the dvd+r format....hence the minus sign in dvd-rom right?
I think since the combi drive is old and that dvd-r came out before dvd+r thats why the combi drive cant read the disc. Also i tried a dvd-r in the combi drive burnt by a friend which read ok.
i burnt at 4x since i dont think my comp could hack the 16x burn which requires a 21mb/sec transfer rate!
Will also experiment with other media also like Verbatim, infiniti and TDK.
As for the dvd player not sure why it didnt work. Dvd booklet says disc
should be iso 9660 and video format. Normally if it cant play it it still can 'see' whats on the disc.
i did make sure the disc was closed via the advanced options. I did use the creator classic instead of the recordnow program aswell.
Guess what? DL13 the newest firmware came out 2day, just two afters after i installed DL12....boo hoo
thanks for your help
