However, these new videos come from a different device. Instead of over the air, they are transmitted on fibre, and the result is already an mpeg file, of a huge size, like 12 or more gigabytes. Several resolutions.

but MTS files are also some variant of mpg, so could you ask mediainfo what are the two kind of files, your MTS and your mpg?
There is only a single mpeg file. The mpeg stream comes from the TV station, so it can be faulty on origin, but all samples I tested have problems. Well, all xine, vlc, mplayer... play them fine. cer@Telcontar:~/Videos/Fusion/trabajo> mediainfo Las\ 13\ claves\ del\ Apolo\ 13\ \ Episodio\ 1.mpeg General ID : 100 (0x64) Complete name : Las 13 claves del Apolo 13 Episodio 1.mpeg Format : MPEG-TS File size : 1.04 GiB Duration : 1h 5mn Overall bit rate mode : Constant Overall bit rate : 2 299 Kbps Video ID : 481 (0x1E1) Menu ID : 1 (0x1) Format : AVC Format/Info : Advanced Video Codec Format profile : High@L3.0 Format settings, CABAC : Yes Format settings, ReFrames : 4 frames Codec ID : 27 Duration : 1h 5mn Bit rate : 1 668 Kbps Width : 720 pixels Height : 576 pixels Display aspect ratio : 16:9 Frame rate : 25.000 fps Standard : PAL Color space : YUV Chroma subsampling : 4:2:0 Bit depth : 8 bits Scan type : MBAFF Scan order : Top Field First Bits/(Pixel*Frame) : 0.161 Stream size : 776 MiB (73%) Color primaries : BT.601 PAL Transfer characteristics : BT.470 System B, BT.470 System G Matrix coefficients : BT.601 Audio #1 ID : 482 (0x1E2) Menu ID : 1 (0x1) Format : MPEG Audio Format version : Version 1 Format profile : Layer 2 Codec ID : 3 Duration : 1h 5mn Bit rate mode : Constant Bit rate : 192 Kbps Channel(s) : 2 channels Sampling rate : 48.0 KHz Compression mode : Lossy Delay relative to video : 15ms Stream size : 89.3 MiB (8%) Language : esp Language, more info : Clean effects Audio #2 ID : 483 (0x1E3)-194 (0xC2) Menu ID : 1 (0x1) Format : MPEG Audio Format version : Version 1 Format profile : Layer 2 Mode : Joint stereo Codec ID : 3 Duration : 1h 5mn Bit rate mode : Constant Bit rate : 128 Kbps Channel(s) : 2 channels Sampling rate : 48.0 KHz Compression mode : Lossy Delay relative to video : 15ms Stream size : 59.5 MiB (6%) Language : Volapuk Language, more info : Clean effects Audio #3 ID : 483 (0x1E3)-192 (0xC0) Menu ID : 1 (0x1) Format : MPEG Audio Format version : Version 1 Format profile : Layer 2 Duration : 360ms Bit rate mode : Constant Bit rate : 192 Kbps Channel(s) : 2 channels Sampling rate : 48.0 KHz Compression mode : Lossy Stream size : 8.44 KiB (0%) cer@Telcontar:~/Videos/Fusion/trabajo> -- Cheers / Saludos, Carlos E.
