|

|

In some instances, subtitles may not appear properly in sync with the A/V stream
|
||||
when using hardware decoding ('-vc mpegpes'). This is a known bug. The em8300
|
||||
will also improperly handle subtitles that are too big, and may hang for a second
|
||||
or two. At this time, the only workaround is to use '-vc mpeg12' when viewing
|
||||
DVDs with subtitles.
