Hauppague HVR-2250 "Line-In" recording issue

[PanoGuy]

Hello:

I'm a newbie, and I've been lurking the boards for a while now - I have an issue that I'm hoping someone could solve:

Whilst in GB-PVR, when I record from the S-Video spigot on the HVR-2250, I have an issue where my video processing packages (TMPGEnc 4.0 XPress, DVDLab Pro, & MPEG Video Wizard, to name 3) don't "see" the entire recorded video.

As an example, I recorded a 55 minute/1.9 gig MPEG2 video from VHS, which on all the above 3 packages show the video as only being 12 mins, 27 seconds long. VLC media player will play all 55 minutes worth, so I know that it's there. I've captured this same video 3 times, with essentially the same result.

I initially thought that it must be the MPEG2 encoder - which is a hardware encoder on my card, but when I record the same VHS, thru the same S-Video spigot, using WinTV (YUCK!!!), my above 3 processing packages "see" the entire captured file.

I tried "fixing" the header information with several freeware apps, to no avail... Does anyone have any suggestions or thoughts???

Thanks much in advance! -J.
