What format should I use, please?

[#1]

You can make the video frame rate as fixed or variable.

I use the default 160kbps for the audio rate on my TV because audio typically uses no more than 8% of the AV file size.

MPEG2 video isn't a great codec to use. If the bitrate is set too low the picture will end up "blocky".
I forget what default options are set in Any Video Converter (I always setup a manual config with that program).
Options to look out for are in this order (best to worst):
Video codec
MPEG4, XviD, MPEG2
Audio codec
MP3, MPEG2 (to be matched with video MPEG2)
File formats to use are:
.mpg - for MPEG4/2
.avi - for XviD

The MediaInfo details suggest that video is already in MPEG4 so could be just copied through but some low end tech won't play it as they only support 1 ref-frame (yours has 2). As for audio AAC does not look to be supported by your TV, so that definitely needs to be converted (correct term is "transcoded").

I use handbrake to give a container format of MP4,

A video format of MPEG4, codec avc1, 4 ref frames, bit rate of 2,000kbps

Audio format of AAC

Subtitles of SRT

Roughly 1GByte per hour.

I wasn't specifically replying to you @VileReynard, the mobile version of this forum can't specify a reply to anyone else if there's only one post on the second page.
Anyway, those settings you've mentioned won't play on @shutter's television, it's not supported.

@RPMozley  & @VileReynard  thanks for your input... I am sure it will be useful to someone else who reads this thread...  however... my reply 15

Edited at the end, shows a really simple and effective solution to my problem... I just drag & drop up to 10 files on to the "Video Converter" part of the suite of "ATubeCatcher"... set the output file , and the output destination... then click on "convert"... job done... ( almost )... I then copy the folder/files to the USB stick...

stick that in the USB slot... chose "source" USB..  and go from there... it`t so simple, no bothering with containing thingys or bit rates  ....
