local dvd cover thumbnail image higher quality?

Is there a way to make the local dvd cover thumbnail image higher quality? I have my own pictures, but they don't look very good after serviio shrinks them down. I know its not my PS3 that is making the images look bad because i used a different media server before and that made them look good but it couldn't handle a lot of movies.
Thanks

It's a DLNA standard to have the resolution shrinked down. Your other server was breaking this standard. It's possible that some devices support higher resolution but Serviio will not go down this route.

Thanks for the fast reply. Its not a big deal. This is the best media server I've found so I'm sticking with it.

I complete understand Serviio will follow the DNLA standard requirements but can a user change this to high res for personal use?

If so how can this be done?

It would break playback on some devices. Serviio saves only 1 version of the thumbnail so if it saved a high res version it would then break on other devices in your home. So no, won't be doing this.
