    The audio you have in the AVI files is heavily compressed mpeg1 layer 3 (MP3). that’s why the audio is muffled.

    If you have the original vobs then you have the original video and audio.

    As to fast forward Humax boxes rely on sidecar files (.nts) to provide this sort of capability. The File System in the freetime boxes is encrypted so the file arrangements isn’t known.

    If the DVDR creates a menu structure the first .vob will normally be the menu. You can check on a PC, many media players will load and play vobs. If you don’t have one try VLC Player.

    It’s going to take some experimentation.

    First step is copy one of the .vobs to a usb drive and change the file extension to .mpg.

    Can the HDR play it back ?. Can you fast forward it ?

    No attachment by the way.

    The problem is obvious from the files. Not sure how you recorded the content but the video resolution is very low (only suitable for display in a small window on a PC), you must have used a very low quality option, assuming they were recorded from a broadcast source. If they were recorded from the internet than you may have the original very low quality.

    SD TV uses mpeg2 at a resolution at best of 720 x 576 pixels. The first figure can vary but there will always be 576 vertical lines (576i).

    Your content has only 288 vertical lines.

    I assume you have your box connected to a HD display with a 1920 x 1080 display.

    You are starting with an image that has just 353 x 288 pixels and the box has to invent the missing pixels to create a 1920 x 1080 image. You have thrown away approx. 83,000 pixels from the original recording, and without the original content you cannot get them back other than pure guesswork.

    As an example I grabbed a frame from a 1920 x 1080 movie and saved it. I then resampled it to your 288i size. Have a look at the two (zoom in to fill your screen)

    I am very grateful for your time and effort on my behalf.

    I see what you say regarding quality. I do not know why the resolution is so low, almost as if from a video camera (old).

    The original recordings were high speed copied to the DVD from the old recorder and provided the Video_ts folder I now have. They took 20 minutes to copy 6 hours and finalize and presumably they are originally stored on the recorder HDD in the same form, but don’t know how to actually access them any other way.

    The vob files are typically 1.3GB per film against uncompressed about 11GB per hour. Any changes in

    I have just opened another DVD at random from the same HDD/DVD recorder and it contains a folder DVD_RTAV in which is VR_MANGR.IFO & VR_MOVIE.VRO 4.2GB 3hr 17mins.

    ??? it locks up Mediainfo.

    The only other thing I can add is that recordings to HDD were invariably done at longest play to get max time and then 6hrs placed on each DVD

    There’s two problems.

    1 The recording you opened has been made in a format that you can modify after recording (Usually called VR mode). They should have been made in DVD-Video format.

    http://en.wikipedia.org/wiki/VR_mode

    2 Using longest play means maximum compression hence low bitrates and the major reduction in resolution. A single layer DVD blank can hold at best around 2hrs of good quality SD content and about 20-30 minutes of 1080i in AVCHD format. Full quality mpeg2 576i should use about 2GB for each hour of recording. You have 6hrs in about 4GB.

    Have you still got access to the original source of the video ?.

    Good morning, no the only video is the video_ts folders now on the DVD’s or the MKV’s of some 150 of the films on HDD. There are some that seem to have higher pixel size but it is clearly random on the choice when first recorded. The aim was to keep as many films as possible in as small a space as possible, now clear to me, resulting in the lowest quality. Some 200 DVD’s each with typically 3 films (including the 3 full Star-Trek series if you like that sort of thing).

    Do not get me wrong, they are reasonable to watch due to something the TV or Humax is doing to them. So I am back to getting them to the format that my tests show works correctly without locking up or jumping on fast fwd etc. Oddly ts only goes as far as x4.

    I must reiterate my gratitude for your time and knowledge.

    [Edit] And change the sound from mp3, but do not know what to.

    Try TSmuxerGUI to see if it will open a file with a MP3 audio track and the same video with an ac3 one. Deselect the MP3 audio track and the video track you don’t want and remux to a .ts file.

    So far I have tried as previously suggested…

    TSmuxerGUI to convert 2 VOB’s to ts.

    Although it worked and does play, as mentioned before ts only fast fwd to x4 and does not fast rew at all.

    [Edit] Thus the final suggestion now pointless.

    Doesn’t the right and left cursor keys work to skip forward and backwards ?

    Yes… skip being the operative word.

    I use the double fwd and back arrows as on a video player to alter the speed of movement up to x32.

    The working format does this correctly all the way to x32 and back smoothly.

    ts only goes fwd x2 and x4 no further and does not even go to x2 in reverse.

    Additional info… the left cursor key skips forward not back with ts format

    They work in the correct way with all my files (Which are all transport stream). I also get 32x (Just tried it on a 1080p24 movie file) playing back from usb.

    Give me a little time I will upload a short test clip just to check there isn’t an issue with your box.

    I don’t know what to say except it doesn’t on mine unless it is MP43. Maybe it depends what the ts was originated from or something, you would be the one to know, not me. I don’t have any HD to try. The only thing I could try is to record from iPlayer on the Humax and feed it from scart to my Panasonic recorder at SD then copy that to HDD and play it. I know that that setup works to record On Demand because it cannot be recorded on the Humax itself.

    So since I seem to be stuck with it and need the best way to transfer to the working format the easiest way without losing any more quality and of course as fast as possible.

    If you can suggest I will be grateful.

    Can you try this clip

    As you can see I can get x32 speed
