problem playing files

[seanc]

i currently have 18gigs of music files stored on my iriver h10 but only a small proportion (about 3gigs) of them are stored under the database in rockbox and when i try to play them through the file browser they say that the files are missing. i could play 14gigs of the total files with the original iriver software and presumed i couldn't play the rest due to them being formatted with itunes.. is this the same with the rockbox are the files formated wrong and is there any setting on the rockbox so i can play all 18gigs of files in the database or otherwise. or do i have to reformat the files, if so how do i go about this??? thank you vwery much

What format are the files in?

[seanc]

the files that are able to be played on rockbox are in mp3 format the files that come up as error are wma.

rockbox doesnt support wma, convert them into an other format.
look at this wiki page (SoundCodecs#Current_status) to see what codecs are currently supportet.

how do i change their format? do i need to download a decoder? what is the best one

Try Foobar

dbPowerAmp Music Converter (freeware) is another one.
