Not installing in root cause video errors?

OK....before anyone yells at me about ALLLLL the other video error topics and why I am starting this, here is the skinny:

I have D7 installed on 2 separate hosting accounts and domains, both with GoDaddy.

One is on a subdomain and installed in a subfolder....and the whole thing works beautifully. Except video uploading! I get the "upload failed error" every time, no matter if I try to embed or upload. I can upload MP3's just fine though.

The other installation is in the root of that hosting account, and works beautifully...INCLUDING the videos. No problems uploading, viewing, commenting, etc.

I know my cron jobs are both set up correctly, even the non-video-working installation, because I am getting the emails and it is set up in the same manner as the video-working installation, albeit with separate paths to the cron.php file.

My ffmpeg.exe and all the folders have the correct permissions, same on both. Since one is working I figure the permissions being set the same on the other are correct.

So basically the only difference is one is a root installation and one is a subdomain in a subfolder. I have emailed GD support and am currently awaiting any response (not holding my breath for any REAL help from them). I have checked and rechecked my settings and don't recall seeing in the specs that it must be installed in the root for the videos to work properly. Anyone encounter a problem like this or have any magic answers for me?

Thanks in advance,

Derek

Well, thanks to all the Boonex peeps for jumping all over that question. 

I moved the account in question to a new hosting account and it works now.  And for all the posts people are leaving in the forums telling GoDaddy users they are SOL unless the have a dedicated or VPS, I have the $6.99 Linux hosting account and the videos and all related to them work fine. ANY PROBLEMS YOU HAVE ARE RELATED TO DOLPHIN and your cron jobs. You need to fix these, not change hosting providers to the ones Boonex pushes.

Interesting...i haven't been able to get D7 videos of a larger size to upload, even though I have created the php.ini, yet the D6 which is in the root will upload larger video files with the php.ini.  Wonder if it will work after I move all the D7 to the root..hmmmm.
