Any way to force frame rate? Audio sync issue on TC-L42E30

Hi guys,

I have a Panasonic TC-L42E30 and have SerViio 0.6.01 running on a Windows 7 32-bit PC.
I use the profile of "Manta WIFI Center" to transcode all videos to the TV through my 100Mbps LAN connection. Most of the videos transcoded by SerViio play smoothly on my TV, except a few. So I played around with my video encoding software. After everything's been ruled out, I found out that whenever I stream Mpeg2 videos that have a higher frame rate than 25fps, the audio tends to loose sync.
I looked at ffmpeg's documentation and it looks like it's possible to add a -r attribute in the command line to make it encode at a fixed framerate. So my ultimate question is this: Is it possible to make SerViio pass that attribute to ffmpeg so that it'll transcode all videos at my desired frame rate?

No, it just keeps the original frame rate.

It would be great if there was a field in the profiles in the transcoding sections where one could specify custom ffmpeg parameters. That would cover this request and possibly others.

Otherwise,it's possible for users to create a custom wrapper for ffmpeg that one can add extra FFMPEG parameters, but that would affect every device that accesses Serviio.
