>occur at specific frames (e. 00:15:08, 00:22:12, etc.).
Hmm... have you expanded your timeline and looked at the frame before and on and after those times to see if there is a file glitch?
Are you sure you do not have something running in the background that could be "stealing" the computer's focus away from video work for an instant?

Win7 64bit Crashing and "a" fix http://forums.adobe.com/thread/580435?tstart=0
As Bill says, the first thing we need to know is what kind of camcorder that AVI came from.
Only video captured over FireWire from a miniDV camcorder produces true DV-AVIs, the ideal format for editing in Premiere Elements.
AVI video from still cameras or video produced by screen capture software, like Camtasia or FRAPS, can have its unique challenges.
According to GSpot (thanks for your nice AVI article): 2 files are 1440x1080, par: 1:1 (i.e. sar & dar: 4:3), MJPG Codec (installed); one file is 1920x1080 (i.e. 16:9).
While the 1440x1080 (i.e. 4:3) format is unusual, PrE9 loads all 3 files either with the Full HD 1080i 30 preset (i.e. 16:9 wt black side-bars) or with that preset edited to 1440x1080 (i.e. 4:3). On the 32-bit Win XP machine they play perfectly. On the 64-bit Win 7 machine PrE9 (& PrE8 & PrProCS5) chokes at specific frames.
On the Win 7 machine, I can locate those frames, cut them out, and the file plays until the next problematic frame.
If I isolate a problematic frame (e.g. delete all pre- & post- frames), that single frame will choke PrE9 on the Win 7 machine but not on the Win XP machine.
The 2 1440x1080 files are transfers from 16mm film (MJPEG Decompressor, Blackmagic 8 bit MJPEG Codec, Decklink MJPEG Decompressor), and about every other frame is a duplicate which I assume is to make the movie frame rate match the AVI frame rate of 29.97. The 1920x1080 file is a video tape transfer.
MJPEG-AVIs are usually video from still cameras which, as I said above, are frequently problematic and need to be converted to DV-AVIs or 1920x1080 MPEG2s before they can be successfully edited in Premiere Elements.
Thank you for the details.
Mixing formats in a single Project will usually lead to problems somewhere. I strongly recommend converting all material that does not match the bulk of your Assets, to match those, or to go the other way (remember, down-rezzing, while not ideal, is usually better than up-rezzing) and match the "larger" material to the "smaller." You might wish to do some small tests of both ways, just to judge what is best for you and for your material.
When everything matches, Import those converted Assets, plus the Assets that you did not need to convert, into a Project with a matching Preset.*
Things will go much more smoothly.
* The choice of what to convert may well hinge on the available Project Presets, i.e. you may need to up-rez some material, rather than down-rezzing other, if there is no Preset for the "smaller" material. Along with the decision based on Frame Size, I would strongly consider the CODEC's. An example would be the MJPEG vs, say AVCHD. I always want to use the CODEC, that will give me the best editing experience and the smoothest editing experience.
Thanks for all your help, but my problem of PrE8or9/PrPro crashing at specific multiple frames in different MJPEG files has stopped. I think the resolution derived from finally deleting (via company-directed folder and registry deletions) a corrupted Roxio Creator 2010 with Roxio 2009 Blu-Ray Plug-in ESD. This RoCr2010 could not be uninstalled normally (Error Code 04C7; perhaps due to a conflict between RoCr2010 & Ro2009BR Plug-in; Roxio Creator Pro 2011 with Blu-ray Playback Plug-In for Creator 2011 installed and works). I doubt that installation of Pinnacle Studio14 had an effect on resolving the problem.
Many thanks to all.
Interesting, and thank you for the report. IIRC, another user had an issue with Roxio Creator, but I cannot find that thread, nor recall any resolution.
I know that some modules in Roxio (and Nero) can interfere with Adobe programs using DVD/BD burners. Those modules are the drag-and-drop packet-writing features, like InCD and DLA (cannot recall which is Roxio and which is Nero). Also, each of those programs has a "watcher/sniffer" module, to monitor any activity in certain folders, and those can get in the way too. While I have Nero installed on my main machines, I have only a small part of that suite, excluding the packet-writing and watcher/sniffer features.
