Unlikely, and I don't think I've seen these associated .THM files on the memory card when I copied the CRW files.

"Note It is important to understand that the file extension is not the sameas the file format. CHDK raws and DNGs are frequently saved with a .CRW or.CR2 extension, but they are NOT in Canon formats that typically use theseextensions."

Presumably, you didn't use CHDK on the G5 (as the G5 allows one to take RAWimages without any firmware modifications).
CHDK also allows one to create raw images on compact cameras like the PS A720 that don't normally allow one to create raw files.

The SX1 does normally (without using CHDK) allow one to create raw files and hence I assumed that by keeping the raw setting to CRW as the default (asopposed to DNG), the resulting raw file would be in the Canon CRW/CR2 raw format. But in retrospect, this assumption was mistaken and I should have opted for the DNG setting (in the CHDK config) for raw files that can easilybe imported in ACR.

The quote below explains my problem:

I think all modern Canons use .CR2. .CRW is an older format that I haven't
seen since my Powershot G-5. The question, though is whether the hacked SX1 is
producing even a properly formatted .CRW file. My copies of DPP and
Zoombrowser don't appear to think that it is.

"Note It is important to understand that the file extension is not the same as the file format. CHDK raws and DNGs are frequently saved with a .CRW or .CR2 extension, but they are NOT in Canon formats that typically use these extensions."

So the CRW file I have is a CHDK raw file and not a Canon raw file.
In the future I will use DNG instead of CRW and that will solve the problem of importing raw files in ACR for any future pics I will take using CHDK.

Also, hopefully CHDK will add an in-camera conversion option for
CRW->DNG, so I can also import these CRW files in ACR.

That does sound like the possibility that's most likely to work.

People at the CHDK forum were able to help me out by entering custom SX1 specs in DNG4PS-2 (the beta version) which allows it to convert the CRW to DNG (and ACR is able to import that DNG).

Thanks everyone here for all suggestions and comments! Problem seems more or less solved now.
