[OTHER] MPEG-2 PS Playback Limitations

[raymondjpg]

MPEG-2 PS files output from VideoReDo TVSuite V4:

1. Rewind button gives exclamation mark (does not rewind).
2. Numeric button skip (10% etc) exits play to file list.

(Firmware 05-01-121220-24-POP-422 (NETWORK TEST) (21.12.2012))

Workaround: Remux into mkv or m2ts container.

that is typical of a file that does not have any header information in it. With no header information how is the player supposed to guess last frame to rr or a percentage to jump to.

To be able to access a ts file with rr/ff and jumping you need sequential header information for the whole stream, most likely your ts output program is not doing this.

OK, thanks for the response. The reason I wish to use the rewind button is to review the past 5-10 seconds of video and/or audio, rather than the 30 seconds determined by the partial time seek function on the D pad.

Try a QuickStream Fix on the file in VideoReDo. That might fix your file. I use VRD and save to MPG all the time, so it's not a an issue with the container.

I think you will find that halfelite is right in that the rewind button as currently configured will not work on any VRD file output to MPEG-2 PS. There is an option to output to MPEG-2 M2TS which I have not tried yet.
