I was not aware that there was a problem with DUNE and PGS streams.
FYI, a PGS subtitle stream is image-based. A sub picture can be "full screen"; in this case the whole subtitle layer has the same resolution as the video.
More commonly used on BD are subtitle pictures that have a limited resolution, depending on how much the line(s) use(s) up space. You can imagine a virtual box around the sub, where the line(s) will just fit in. In these cases there is "positioning data" in accordance with the video's native resolution. Even if the subs are shown just plain centered at the bottom of the video, there is positioning data.
In my experience all DUNE players handle these PGS streams (or SUP files) well. I would rather think that there is something else the matter with your subtitle.
If you would rip, copy and/or remux a PGS stream directly from bluray it will automatically copy the positioning data; it's within the PGS stream itself and your DUNE will play it fine.
Though, in many occasions where SUPs are ripped from bluray, they are converted via OCR into SRT. Positioning data, fontsize, -type and -color data will be lost; pictures are OCR'ed into plain text only. When someone converts srt back into a SUP file, the used software will determine the sub-picture's positions. Default settings can be like just be in the middle, bottom line. Or the software's user has chosen an other setting for sup placement, fonttype, -color etc..
If you would rip a bluray, of which you know it has "special" positioned subtitles, and you would play it on your DUNE, you'll see that positioning is not a problem. I never encountered such an issue with my TV303D.
I can imagine however that a faulty firmware can be the culprit, but I doubt this highly. Maybe that (certain settings from -) ripping software can cause issues.
