@lembas: what is the point in replying when one has nothing to reply ? ;)
/me seriously asking...
@EricxDu:
totem does not exactly have the best reputation as media player. I also
usually use either SMPlayer or VLC. They both provide sufficient buffering to
get a got experience when playing back files from optical media. Be it DVDs
or HD stuff burned to BDs.
Sometimes though the optical drive and / or the media might have issues with
quick spin up time. Even when using a standalone DVD player on the cheap
models there is often a small hickup when you have paused the video and
restart it.
I do not know if you have any special options to finetune the behaviour of
VLC / SMPlayer in regard of buffering / read ahead.
HTH,
Holger
