Converting avi + srt to mp4 with embedded subtitles

[zaphod_es]

The Problem:
I have a Philips Series 3000 LCD TV which, the salesman said, will play video files from the USB port. Now I find that it will only accept mp4 and mpeg4 files with h.264 codec or a wmv file. I have both Ubuntu Linux and OS X but no Windows. To make it even worse the TV has no subtitle support.

The plan:
To convert the avi files to mp4 with Handbrake. Now I find that Handbrake cannot embed srt files. Of course the Philips TV cannot read the srt soft subtitles that Handbrake can include. I did find that Handbrake can embed ssa subtitles.

The questions:
Am I going in the right direction? Is there a better plan?
Is there a good app (preferably Linux) that can convert srt to ssa?

Go easy on me as this is all rather new subject. Thanks

You could use avidemux. Add the subtitle filter and load the srt. Use mpeg4 avc video codec and copy under audio. Save as mp4.
