It seems some users figured out a way to bypass some of the malfunction. For the videoplaying issue corecodec released a new version of the corecodec player. Users reporting an significant increase in framerate. Corecodec is the first manufacturer who is including the Qtv driver in the HTC devices.
For the camera one of the users report that in low light the frames can increase to 20 plus by pressing the sleep button when the camera is active, wait some seconds and press it again so the phone wakes up in the camera application. Multiple users reported this solved the problem for now....
HTC issued there is a patch being build right now. What the patch will include is not yet sure, but at least it is something. Hopefully it will solve some of the issues, but the camera and video performance will most likely not being upgraded....
Also HTC said that in the future their devices will support all the functions of the chipset... yeah right!
In this chapter I will describe all problems currently known with the HTC devices with a qualcomm MSM7200 chipset. Also added some YouTube movies to visualize the problem.
Poor video playback: To be more specific the issue stems from the fact that HTC doesn't supply any generic driver for the video part of the chipset that the phone is based on. The chip in itself has all the support needed problem is that in order to access it you need to use esoteric and closed source platforms instead of the widely used APIs such as GDI (for drawing up the phone interface), DirectDraw (for video playback), Open GL ES/Direct3D Mobile (for 3D gaming) and GAPI (gaming). Acceleration can, supposedly, still be achieved through applications which are programmed for the specific Qualcomm software platforms. Below Enough technical detail, below a YouTube movie to make it clear:
Even simple things like sliding from landscape to portrait mode causes many problems, The tytnII is outperformed by almost any modern phone when it comes to rendering video. Because of the lack of drivers also normal applications work very, very slow. below again a youtube movie witch shows the power of the TytnII during browsing...
The camera also got a very, very bad performance, in bright daylight you can shoot pictures, and they look very good also, much better as previous HTC models. BUT, as soon as it get dark, and even shady, the tytnII performs really worse. you will only have like 3 frames a second and it's impossible to take any normal picture.
This are mainly the biggest issues with the HTC devices supporting a qualcomm MSM7200 chipset. So if you want to use your phone in a normal way, I recommend to look for another devices. And remember, It's not the hardware, because LG managed to work fine with her newest model. Also with a qualcomm MSM7200 chipset. It's because the lack of proper video driver for rendering things....
I advise everyone to contact HTC, they sure are aware of the problem, but they act like their stupid, by sending back very basic e-mails. Below my e-mail and response, below that the contact numbers for HTC. Please call or e-mail them, at the end someone should accept the problem and work it out.

Problem_Description: Dear sir, madam,
I have a htc TYTN II, bought it as office/multimedia PDA. Now i discovered that movies my old phone can't play smooth on my TYTN II. how can this be since the TYTNII got a qualcomm with ati imageon chipset?
after some research i figured out that there are no drivers on the phone supporting hardware acceleration. So it's not possible to watch smooth video and play games.
Are there coming any software updates for this issue? because i think it's a little bit disapointing on a device of 700 euro.
Also the camera refreshes extremely slow (about 2 fps) in preview mode, wich make it impossible to take pictures in other situations then bright sunlight.
I hope to get a answer to my questions soon.
Unfortunately, we are not developing any drivers for that device at this moment.
