I received my TBS 8921 a few days ago and finally have had some time to install it and play a bit. First impression is...it is rough and needs some refinement but I am excited that Cody is willing to work with the community to smooth out the wrinkles.
First off I wanted to see if the card works with my main application Dvbviewer4.6.0.1 and it seems to work fine so far, I haven't noticed anything major, channel switching is a bit slower than my Prof 7301 but is acceptable. Works well with Transedit 3.6.3.0, operating my DiSEqC 4x1 switch and sending DiSEqc1.2 commands to my Gbox3000 positioner.
I haven't had much luck getting Dvbdream V1.5e working... with the bda.dev included on the cd, I can get a channel to play but only after a delay of 10-15 seconds after selecting it...DiSEqC switching works but as soon as I try to move the dish to another satellite, the application freezes solid requiring a hard re-set of the machine..this is very predictable, happens every time. I should mention I"m using raw DiSEqC commands to an actuator, don't know if this happens with USALS motors also.
Rel says he has a patch to fix a motor problem that freezes the machine with the TBS 6921 card, hopefully it will also fix the 8921...I"ve posted the problem on his forum.
With Altdvb and the newer v0.2.0.8 bda interface, I am able finally to get cband as well as ku band working, DiSEqC works fine, I did notice the application would close un-expectedly from time to time. A few times the cpu usage was around 40% which is high, it seldom ever exceeds 20% even with h.264 hd. Changing codecs, renderers didn't seem to make any difference....more testing is necessary.
I loaded up the TbsViewer program that comes on the cd but it looks like a stripped down version of DvbViewer and since the card works well with DvbViewer I'll just stick to that.
The card is recognized with the bda source from the TBS site and will tune channels with TSReader but it takes a long time to tune and misses a lot of muxes, I am curious if TsReader is just timing out? I can tune muxes with Dvbviewer and the 8921 but Tsreader can't get a lock with the same card and same mux. This happens quite a bit, I'd say maybe 50% of the time TSReader can't lock on to signals that Dvbviewer can lock and play.
I played a bit with the blind scan tool but will post some comments about that in the 6921 release date thread.
All in all, I like the card, most importantly it works with Dvbviewer so I can continue to use it as my main application and play on the side with the blind scan tool.
EDIT:
Forgot to mention, I also tried the card with ProgDVB6.51.01, it recognized the 8921 and I was able to set it up with the motor and 4x1 DiSEqC switch in the configuration section but the program crashes when I try to scan any satellite...I could never get past the scanning, crashed every time.
