Has an 'Avseq01.dat' file on a VCD lesser quality than the m

[Moon@Uni-Duisburg.de]

Well, I wanna burn my Family Guy mpegs to VCD and I would like to know if this results in any quality loss.

So if I borrow this VCD to a friend (who doesn't have a VCD-player) and he copies the 'Avseq01.dat' files to his HD and renames them to mpeg, does he have the very same quality as with the mpeg I originally started with?

TIA

You cannot just copy the *.dat files to the hard drive and play them. You can however convert them using VCDGear which has a dat-->mpeg converter. And there is no quality loss.

Aldus4, you can open the .dat file with mplayer2 by double clicking on it. As for the question of quality loss, it depends on the encoding settings you use.

Yes, I did actually mean converting the dat back to mpeg, that there is no quality loss. Some players will open and recognize a dat file - others don't, therefore it's always better to reconvert a dat file back to mpeg1, especially if "Moon" is planning to do this on someone else's PC.

What I did was to copy the 'Avseq01.dat' to my HD, rename it to 'mpg' and play it in Microsoft Media Player. So is this the same mpg I had when I started to make a VCD of it or is the 'Avseq01.dat' file a file that has been altered for the VCD and is not identical with the original mpg?

I did not convert it or anything, I just played it back. So if do it like this, does the dat-file have lesser quality than the original mpg?

If yes I would burn VCDs for myself and instead of borrowing the VCDs to a friend I would burn a regular CDROM for him with the mpgs on it which would be a double amount of time...

As you chose the easy way - yes - it is of lesser quality as probably the headers of the original mpeg file are missing. - That's why you convert the dat to mpeg, and not just rename it!
