With the arrival of wide-screen tv, I obviously need to adjust my capture format profile to reflect the 16:9 aspect.

Can anyone advise what capture size I should be using?

Previously, I have used 720 x 576 for recording and burning onto DVD, but now, any wide-screen film is horribly squashed

I am using a Leadtek WinFast TV 2000 XP Expert TV Tuner

720x576 is fine.  You'll need to ensure your DVD project is set to 16:9 so your dvd player knows it's a widescreen programme and display it correctly.

Are you using the built in write-to-disc feature in the Leadtek software?  If so, I'm not sure where (or if it has) that setting is.
Or are you using a seperate DVD writing programme to save the files to DVD?

The recorded video is saved directly to the HDD on my PC via the TV tuner card.

No matter what programme I use to playback the recorded video clip, it appears squashed - therefore it has to be the 720 x 576 capture format that is at fault.

No??

The only options available to me using the MPEG-2 Codec are:

192x144
352x288
384x288
384x576
720x576
758x576

720x576 is the standard resolution. It doesn't matter if its 4:3 or 16:9.

The playback software needs to play it back in 16:9 aspect ratio. More than likely your TV card isn't recording the file with any 'flags' as such to tell your playback software it's in 16:9.

In your playback software (depending what programme it is) you should be able to select 16:9 under it's aspect ratio settings.

If there's no flag or desriptor set in the recording to tell the program it's a 16:9 recording, it will treat it as a 4:3 recording.

Zippity, I was confused about this as well when I first started mastering DVDs from a DV camera, because I was thinking in terms of computer pixels which are square, but video ones aren't necessarily so. The PAL DVD standard is 720x576, which is roughly 4:3 if the pixels are square. When a DVD is mastered in 16:9 the signal is still 720x576 but a flag is included that tells the display to stretch the horizontal pixels to give a 16:9 aspect ratio. Most widescreen TVs or projectors have a setting you can change between auto (determined by flag) and user defined, either 4:3 or 16:9. There are other standards like 384x576 which again contain a flag that tells the display how much to stretch the horizontal dimension to achieve either 4:3 or 16:9 aspect ratio.

If you want to see for yourself, have a look at ALT TV (Sky ch65). Some of their music videos have been uploaded to the server in 16:9 but the signal is transmitted without a widescreen flag so the images look streched when viewed in 4:3. If you change your TV to widescreen manually they display correctly, but then the next video looks squashed down until you change back to 4:3 again.

Most DVD mastering software like Roxio or Nero will ask whether the project you are creating is 4:3 or 16:9 and set the flag accordingly. If your capture software doesn't have this option you will need to adjust your TV manually.

You were on the right track

The answer was simple, as this reply from another forum indicated:

"Just use DVD Patcher and "patch" 4:3 to 16:9 on your original mpeg 2 file
www.videohelp.com/tools/DVDPatcher

Then load to TMPGenc author, and so on as always"
