12mb files become 6mb in Ulead Movie Factory 2?

[swadey]

Hi all,

I'm trying to burn DVDs from mpeg program streams that have been recorded using a Hauppauge WinTV PVR 250. I record these streams at 12mb CBR in Mpeg2 Program stream format. When I use Ulead Movie Factory the resulting DVDs use exactly 1/2 the space of the original mpeg2 file. In my disc template, I've checked the "Do not convert compliant MPEG files" checkbox, yet it seems that conversion is done nonetheless (it takes about 3 hours to convert and burn at the highest quality settings).

Is this because the source is interlaced? If so, how do I keep Ulead Movie Factory from making these progressive? How do I preserve the bit rate? Is there some trick that I'm missing? If this isn't what's happening, what might be going on?

Thanks!

The 'Do not convert compliant MPEG files' option only works if your project settings match your video (incl the audio settings).

Before making the DVD, click on the 'project settings' box at the bottom of the screen, select 'Change MPEG settings' and 'Custom' and make sure that the Frame Size, Video Data Rate and Audio Format all match your original MPEG file.

99% of the time this will ensure that MF will not re-encode, however there is still that annoying 1% of cases that refuse to play by the rules.

From what I have read 12mb/s is NOT dvd compliant.

AFIK project setting is used by mf-2 as templete to re-incode if necessary and to determine adequate disc/hdd space, if your file is dvd compliant and the check box is checked, it does not re-encode.

If you leave project setting at 8mb/s and try to cap at 4mb/s or less for 2 hr timed cap it will give pop-up with max cap based on project setting
