Converting MPEG-TS to, well, MPEG

[gdt]

Digital TV uses MPEG Transport Stream, which is a container for video designed for lossy transmission, such as radio. To save CPU cycles, Personal Video Records often save the MPEG-TS stream directly to disk. The more usual MPEG is technically MPEG Program Stream, which is designed for lossless transmission, such as storage on a disk.

Since these are a container formats, it should be possible to losslessly and quickly re-code from MPEG-TS to MPEG-PS.
