1/3 Of AVI is Corrupted

[ndemon]

Firstly, sorry if this has been covered before, by I searched throughout the forum and guides for corrupted avis, and nothing seemed relevant or helped
I recently used DScaler to capture a couple of hours (3) in MPEG2 (Svcd?) format at 320x240. Now the file is about 4GB, and after reading around it seems AVI can only be a max of 2GB (not sure about the validity of this).
So at first I assumed the entire file was corrupted, but it seems only the first third is, after which I can view the rest of the captured movie (I used VirtualDub to do this as Windows Media player wouldn't really play it)

Is there anything I can do to fix the first third, as what I need is on the corrupted portion (since the capture was not a scheduled one, I just stopped it when i returned to my comp ) and re-encoding isn't an option as the source was cable tv

TIA

I think you've misread or confused things you've read. An avi can be any size. The file size may be limited by your operating system with the difference being betweem Fat32 and NTFS.

You have not posted your computer specs. You don't explain what you call "corrupt". So there may be nothing to "fix".

Windows XP
DScaler 4.1.7 to encode
512 mb rab
40gb + 80gb(this one has the file)
NTFS on all drives

By corrupted I mean gspot v2.21 states I have a Corrupt AVI header, 3 compatiable codecs, PCM audio, and rendering is successful

if any more info is required please tell me

Is it an AVI or an MPEG? you said it was both.

Load it up in VDUB and check for corrupt video then fix it if it's an AVI.

First, try another software player. Never let Virtual Dub or Media Player have the last word. Try PowerDVD or WinDVD before you declare corrupted video.

Well afaik the file is an avi file using an mpeg codec, I don't really know how this works but if I name it .mpg tmpegenc and other mpeg tools do not recognise it.
VDub reports "Error decompressing video frame: xxx: An unknown error occurred (may be corrupt data). (error code -100)" from frame 0 to about frame 90000., as for "fix it if it's an AVI" that's what I don't know how to do.
I've tried playing it in powerDVD which shows it as garbled squares (kinda like artifacts)
