[quote=Mike109;2082757]I understand Womble does not re-encode. However I saw a comment elsewhere that Nero may still re-encode. Is this possible?[/quote]Womble does re-encode if you change the output format; for example if you try to change the aspect ratio (4:3 to 16:9), quality setting (ie the bitrate, going from HQ to SP settings), or even to another codec (MPEG-1). If you import a recording from a DVD recorder in SP and just do some plain editing, MPEG-VW will not re-encode. It’s one of the advantages that make it so attractive to use.
I am pretty sure that the Nero Burning ROM part of the Nero suite has no re-encoding capability, so burning to disc using it will only reformat the edited MPEG-2 recording into the multiple .VOB (video object) files, and add the .IFO and .BUP information files.
[quote=Mike109;2082781]I just cut out commercials from a DVD-R that was originally made in the 1 hour XP mode on my stand alone DVD recorder. The program was 56 minutes long and looking at the disc it was just about full, as it should be.
The edited program is 43 minutes long but only filled about a half inch worth of burning area, or less than half burned!!
I previously did a 1 hour program that was originally recorded in the 2 hour SP mode. The edited 45 minute program burned about half a disc, which looks about right.
How come the XP mode program was reduced in size?[/quote]Probably the “XP” mode of your recorder is not compatible with the DVD Video standards (the quality of which is roughly equivalent to SP in DVD recorder terms), so Womble must have re-encoded it down to SP level if you asked it to make a DVD or kept the default settings. Can you please clarify which version of MPEG-VW you are using; either the ‘DVD’ version or just the ordinary one?
