Handbrake suddenly not recognizing mkv files

[georgegmd]

I have processed twenty bluray videos without difficulty (ext USB LG 12LU30, MKV version 1.6.7) and have had Handbrake translate them to m4v files that play in iTunes without any problems.

Yesterday I processed four Harry Potter movies. One worked fine (the first movie). The three other MKV files play fine using VLC. However, Handbrake now tells me "No Valid Source Found" when I try to convert any of the three to m4v.

Any suggestions are greatly appreciated.

Please post mediainfo output for any file that fails.

How many streams? The total number of streams (video, audio and subtitles) should not exceed 20.

Thanks, that worked.
