Is there anything which could be done to performance tune this further on Vita?
There's something about PlayStation Doom, PlayStation Final Doom and PlayStation Doom Master Edition where they all have the same problem with audio being lost on state restoration. The nearest I have to an answer is going back into the main menu immediately resets something which needs to be...
I spoke too soon. Am still having to use the workaround at the start of each level to go into the menu where I select the Main Menu option, save state there, when reloading I go immediately back into the main menu and use the password screen from there. That gets around the audio being lost.
Interesting. Handbrake has defaults which are slightly outside what's needed for ripping PAL DVDs.
I'm guessing Make MKV is doing video at CRF 24 and audio at 128k.
Animation content is likely to rip from DVD without issue, especially if it's US DVDs being ripped to 720x480. It's just some content has trouble at 576p and moving the audio codec to MP3 frees up CPU.
The defaults in Handbrake cause frame drops in many videos when doing 576p (especially the CQ setting). This is from a previous post, where I worked out better settings. The two bits which matter are increasing CQ and using MP3 for audio. This accommodates the weak CPU on Wii.
"Preset: Very...
Not sure.

There's an option to encode video using an average bit rate in Handbrake ('Avg bitrate' in the Video tab). Annoyingly, this is an average, as opposed to a maximum in ffmpeg.
I had a go at doing this at 1200K using the default...
I've been looking into directly ripping DVDs using ffmpeg, whilst combining the approach I suggest. It's essentially this (DVD Drive is X:\ ) :
c:\ffmpeg\bin\ffmpeg.exe -i x:\VIDEO_TS\VTS_02_1.VOB -acodec libmp3lame -qscale:a 4 -vcodec libx264 -profile:v main -crf 14 -maxrate 1600k -bufsize...
A bit of further context about downscaling a 1080p file using this:
c:\ffmpeg\bin\ffmpeg.exe -i input.mp4 -acodec libmp3lame -qscale:a 4 -vcodec libx264 -profile:v main -crf 14 -maxrate 1600k -bufsize 2M -vf scale=720:576 output.mp4
This dynamically targets CRF 14 most of the time at a bit...

To answer your question again. For context, a typical IPTV 1280x720 stream will be at about 3000k. On 720x576 it's not worth going above CRF 13 or -qscale:a 2 (higher audio quality). You really are at the boundary point of what the device can do. It's likely this could be...
c:\ffmpeg\bin\ffmpeg.exe -i input.mp4 -acodec libmp3lame -qscale:a 4 -vcodec libx264 -profile:v main -crf 14 -maxrate 1600k -bufsize 2M -vf scale=720:576 output.mp4
Bump up -maxrate 1600k to say -maxrate 1800k
That said, it's CRF which most influences quality. CRF 14 is pretty fkn high and on...
