With some of my ISOs, pressing fast forward skips to the next title instead of actually fast forwarding (Sony BDP).
As an experiment, I set a title in question to pre-transcode to M2TS... voila, I now had working fast forward and rewind.
Any ideas as to why this is happening?
I am guessing that your Sony player can't do FF/RW for VOBs. This is one of the reasons I rip all of my Blu-Ray and regulat DVDs into the m2ts format. I realize it won't help you for normal DVDs if you are using ISOs.Quote:

When transcoding on-the-fly, many devices don't like FF/REW. Right-click on the DVD video in Mezzmo and click 'Get FFmpeg Information. Post that information here.

As another experiment, I chose the "Use Original File" (no transcoding) option, and the file played fine, but again with no FF/REW.
With some of my DVD ISOs, FF/REW work.
Thanks for the FFmpeg information. The file looks fine for your Sony BDP to play natively, so Jeff may be right - it may be a limitation of your Sony BDP when playing VOB/MPEG-2 files. To be absolutely sure, turn on logging (see http://forum.conceiva.com/showthread...nostic-logging) and restart your Mezzmo server. Reproduce the FF/REW problem on your Sony BDP and then stop your Mezzmo server and exit Mezzmo. Zip up all the logs and email them to us at support [at] conceiva [dot] com.

[EDIT]
After even more research and testing, I've decided to use ByteCopy's "Directly Copy" option for DVDs and BDs (instead of making ISOs):
- FF/REW are very fast with a .vob created from a DVD (I expect the same from .m2ts from a BD).
- Copying this way is much faster than using the MKV option (no need to convert to H.264).
- No transcoding is required during playback.
Thanks for sending the logs. We'll analyse them and respond back shortly.
Regarding your further testing, I guess you may have found a good format that your Sony BDP can play well.
