I have ripped all my DVDs to my Synology server using Handbrake. The Humax is connected via ethernet to the server. All the DVDs were ripped to MP4 using Handbrake's 'High Profile' setting with the Large File Size box unchecked. All the files that are below 2GB play just fine through the HDR Fox T2. However, all the files that are bigger than 2GB cause an error message: 'Cannot support this file format'. (Note that no files are larger than 3GB) All the files, no matter their size, play on other devices in the house (e.g. iPad, Android), which suggests there's nothing wrong with the files themselves. I was confused about why files smaller than 2GB would play on the Humax but not those greater than 2GB so I wrote to Humax's Customer Support. Their answer was that they didn't have a problem at their end so the problem must be in the way I did the ripping (and they hinted that there were well-documented problems with using Handbrake, something I've not been able to verify). They dismissed my comment that if the files were all created in the same way, and that files smaller than 2GB played without any problem, then the Humax must be doing something differently with files greater than 2GB. Wondering if this was a limitation of the factory firmware, I've just installed the custom firmware but the issue is the same. It seems that member ACS had the same issue in July 2012 and it was suggested the problem was with his NAS. As explained above, I don't think that's the problem, rather that the Humax is doing something different with files that are larger than 2GB. I'd be grateful to know if anyone else has had this problem and even more so to find a workaround. Many thanks in advance.
