VobSub compatibility problem with Oppo BDP-105

[haggis999]

If I rip one of my commercial DVDs to an MKV file the embedded VobSub subtitles will play without any problem when streamed via DLNA to my Oppo BDP-105 media player.

However, the Oppo does not handle the standard SUP subtitles within a MKV rip of a commercial Blu-ray disk. I have therefore used BDSup2Sub to convert the SUP subtitles to the VobSub format (.idx file) and then used MKVMerge to remux the movie using this newly created IDX file.

The Oppo is able to display the VobSub subtitles in the modified MKV file when streamed via DLNA but the colours are wrong. The main text colour is a mid green instead of white. Even worse, the text edges are also in this same green colour, which makes adjacent characters bleed into one another. These subtitles can be very difficult to read.

I have reported the problem to Oppo but have not yet received an answer. However, the fact that standard DVD subtitles work fine while VobSub titles created by BDSup2Sub do not, suggests that maybe the problem lies with BDSup2Sub.

Your advice and comments would be appreciated.
