first, check if there's new FW, update if there is.
next, depending on media player you can output via SPDIF audio (if your TV has a optical in)
or HDMI, set your NMT accordingly.
check your audio output settings, if you are set to raw, play with other options that is NOT raw.
every NMT claims it plays all format, so check out the NMT thread
Sorta new with this as I just picked up a WDTV this year and mainly pissed that some of my downloaded videos with DTS audio and some other audio format wont play via my LCD TV.
So...my question would be is that what media player can make things easier for me? I don't want to invest on a Home theatre setup as i just want to keep it simple. Recommend na rin what model I should look for that plays all video format...and of course, allows me to play DTS etc audio via TV only.
Thanks.
